+ *
+ * This is [protobuf-c], a C implementation of [Protocol Buffers].
+ *
+ * This file defines the public API for the `libprotobuf-c` support library.
+ * This API includes interfaces that can be used directly by client code as well
+ * as the interfaces used by the code generated by the `protoc-c` compiler.
+ *
+ * The `libprotobuf-c` support library performs the actual serialization and
+ * deserialization of Protocol Buffers messages. It interacts with structures,
+ * definitions, and metadata generated by the `protoc-c` compiler from .proto
+ * files.

+ * \page gencode Generated Code
+ *
+ * For each enum, we generate a C enum. For each message, we generate a C
+ * structure which can be cast to a `ProtobufCMessage`.
+ *
+ * For each enum and message, we generate a descriptor object that allows us to
+ * implement a kind of reflection on the structures.
+ *
+ * First, some naming conventions:
+ *
+ * - The name of the type for enums and messages and services is camel case
+ *   (meaning WordsAreCrammedTogether) except that double underscores are used
+ *   to delimit scopes. For example, the following `.proto` file:
+ *
+~~~{.proto}
+        package foo.bar;
+        message BazBah {
+            optional int32 val = 1;
+        }
+~~~
+ *
+ * would generate a C type `Foo__Bar__BazBah`.
+ *
+ * - Identifiers for functions and globals are all lowercase, with camel case
+ *   words separated by single underscores. For example, one of the function
+ *   prototypes generated by `protoc-c` for the above example:
+ *
+~~~{.c}
+Foo__Bar__BazBah *
+       foo__bar__baz_bah__unpack
+                     (ProtobufCAllocator  *allocator,
+                      size_t               len,
+                      const uint8_t       *data);
+~~~
+ *
+ * - Identifiers for enum values contain an uppercase prefix which embeds the
+ *   package name and the enum type name.
+ *
+ * - A double underscore is used to separate further components of identifier
+ *   names.
+ *
+ * For example, in the name of the unpack function above, the package name
+ * `foo.bar` has become `foo__bar`, the message name BazBah has become
+ * `baz_bah`, and the method name is `unpack`. These are all joined with double
+ * underscores to form the C identifier `foo__bar__baz_bah__unpack`.
+ *
+ * We also generate descriptor objects for messages and enums. These are
+ * declared in the `.pb-c.h` files:
+ *
+~~~{.c}
+extern const ProtobufCMessageDescriptor foo__bar__baz_bah__descriptor;
+~~~
+ *
+ * The message structures all begin with `ProtobufCMessageDescriptor *` which is
+ * sufficient to allow them to be cast to `ProtobufCMessage`.
+ *
+ * For each message defined in a `.proto` file, we generate a number of
+ * functions and macros. Each function name contains a prefix based on the
+ * package name and message name in order to make it a unique C identifier.
+ *
+ * - `INIT`. Statically initializes a message object, initializing its
+ *   descriptor and setting its fields to default values. Uninitialized
+ *   messages cannot be processed by the protobuf-c library.
+ *
+~~~{.c}
+#define FOO__BAR__BAZ_BAH__INIT \
+ { PROTOBUF_C_MESSAGE_INIT (&foo__bar__baz_bah__descriptor), 0 }
+~~~
+ * - `init()`. Initializes a message object, initializing its descriptor and
+ *   setting its fields to default values. Uninitialized messages cannot be
+ *   processed by the protobuf-c library.
+ *
+~~~{.c}
+void foo__bar__baz_bah__init
+                     (Foo__Bar__BazBah *message);
+~~~
+ * - `unpack()`. Unpacks data for a particular message format. Note that the
+ *   `allocator` parameter is usually `NULL` to indicate that the system's
+ *   `malloc()` and `free()` functions should be used for dynamically allocating
+ *   memory.
+ *
+~~~{.c}
+Foo__Bar__BazBah *
+       foo__bar__baz_bah__unpack
+                     (ProtobufCAllocator  *allocator,
+                      size_t               len,
+                      const uint8_t       *data);
+~~~
+ *
+ * - `free_unpacked()`. Frees a message object obtained with the `unpack()`
+ *   method. Freeing `NULL` is allowed (the same as with `free()`).
+ *
+~~~{.c}
+void   foo__bar__baz_bah__free_unpacked
+                     (Foo__Bar__BazBah *message,
+                      ProtobufCAllocator *allocator);
+~~~
+ *
+ * - `get_packed_size()`. Calculates the length in bytes of the serialized
+ *   representation of the message object.
+ *
+~~~{.c}
+size_t foo__bar__baz_bah__get_packed_size
+                     (const Foo__Bar__BazBah   *message);
+~~~
+ *
+ * - `pack()`. Pack a message object into a preallocated buffer. Assumes that
+ *   the buffer is large enough. (Use `get_packed_size()` first.)
+ *
+~~~{.c}
+size_t foo__bar__baz_bah__pack
+                     (const Foo__Bar__BazBah   *message,
+                      uint8_t             *out);
+~~~
+ *
+ * - `pack_to_buffer()`. Packs a message into a "virtual buffer". This is an
+ *   object which defines an "append bytes" callback to consume data as it is
+ *   serialized.
+ *
+~~~{.c}
+size_t foo__bar__baz_bah__pack_to_buffer
+                     (const Foo__Bar__BazBah   *message,
+                      ProtobufCBuffer     *buffer);
+~~~
+ *
+ * \page pack Packing and unpacking messages
+ *
+ * To pack a message, first compute the packed size of the message with
+ * protobuf_c_message_get_packed_size(), then allocate a buffer of at least
+ * that size, then call protobuf_c_message_pack().
+ *
+ * Alternatively, a message can be serialized without calculating the final size
+ * first. Use the protobuf_c_message_pack_to_buffer() function and provide a
+ * ProtobufCBuffer object which implements an "append" method that consumes
+ * data.
+ *
+ * To unpack a message, call the protobuf_c_message_unpack() function. The
+ * result can be cast to an object of the type that matches the descriptor for
+ * the message.
+ *
+ * The result of unpacking a message should be freed with
+ * protobuf_c_message_free_unpacked().

-/*! \file
- * \mainpage Introduction
- *
- * This is [protobuf-c], a C implementation of [Protocol Buffers].
- *
- * This file defines the public API for the `libprotobuf-c` support library.
- * This API includes interfaces that can be used directly by client code as well
- * as the interfaces used by the code generated by the `protoc-c` compiler.
- *
- * The `libprotobuf-c` support library performs the actual serialization and
- * deserialization of Protocol Buffers messages. It interacts with structures,
- * definitions, and metadata generated by the `protoc-c` compiler from .proto
- * files.
- *
- * \authors Dave Benson and the `protobuf-c` authors.

- *
- * \page gencode Generated Code
- *
- * For each enum, we generate a C enum. For each message, we generate a C
- * structure which can be cast to a `ProtobufCMessage`.
- *
- * For each enum and message, we generate a descriptor object that allows us to
- * implement a kind of reflection on the structures.
- *
- * First, some naming conventions:
- *
- * - The name of the type for enums and messages and services is camel case
- *   (meaning WordsAreCrammedTogether) except that double underscores are used
- *   to delimit scopes. For example, the following `.proto` file:
- *
-~~~{.proto}
-        package foo.bar;
-        message BazBah {
-            optional int32 val = 1;
-        }
-~~~
- *
- * would generate a C type `Foo__Bar__BazBah`.
- *
- * - Identifiers for functions and globals are all lowercase, with camel case
- *   words separated by single underscores. For example, one of the function
- *   prototypes generated by `protoc-c` for the above example:
- *
-~~~{.c}
-Foo__Bar__BazBah *
-       foo__bar__baz_bah__unpack
-                     (ProtobufCAllocator  *allocator,
-                      size_t               len,
-                      const uint8_t       *data);
-~~~
- *
- * - Identifiers for enum values contain an uppercase prefix which embeds the
- *   package name and the enum type name.
- *
- * - A double underscore is used to separate further components of identifier
- *   names.
- *
- * For example, in the name of the unpack function above, the package name
- * `foo.bar` has become `foo__bar`, the message name BazBah has become
- * `baz_bah`, and the method name is `unpack`. These are all joined with double
- * underscores to form the C identifier `foo__bar__baz_bah__unpack`.
- *
- * We also generate descriptor objects for messages and enums. These are
- * declared in the `.pb-c.h` files:
- *
-~~~{.c}
-extern const ProtobufCMessageDescriptor foo__bar__baz_bah__descriptor;
-~~~
- *
- * The message structures all begin with `ProtobufCMessageDescriptor *` which is
- * sufficient to allow them to be cast to `ProtobufCMessage`.
- *
- * For each message defined in a `.proto` file, we generate a number of
- * functions and macros. Each function name contains a prefix based on the
- * package name and message name in order to make it a unique C identifier.
- *
- * - `INIT`. Statically initializes a message object, initializing its
- *   descriptor and setting its fields to default values. Uninitialized
- *   messages cannot be processed by the protobuf-c library.
- *
-~~~{.c}
-#define FOO__BAR__BAZ_BAH__INIT \
- { PROTOBUF_C_MESSAGE_INIT (&foo__bar__baz_bah__descriptor), 0 }
-~~~
- * - `init()`. Initializes a message object, initializing its descriptor and
- *   setting its fields to default values. Uninitialized messages cannot be
- *   processed by the protobuf-c library.
- *
-~~~{.c}
-void foo__bar__baz_bah__init
-                     (Foo__Bar__BazBah *message);
-~~~
- * - `unpack()`. Unpacks data for a particular message format. Note that the
- *   `allocator` parameter is usually `NULL` to indicate that the system's
- *   `malloc()` and `free()` functions should be used for dynamically allocating
- *   memory.
- *
-~~~{.c}
-Foo__Bar__BazBah *
-       foo__bar__baz_bah__unpack
-                     (ProtobufCAllocator  *allocator,
-                      size_t               len,
-                      const uint8_t       *data);
-~~~
- *
- * - `free_unpacked()`. Frees a message object obtained with the `unpack()`
- *   method. Freeing `NULL` is allowed (the same as with `free()`).
- *
-~~~{.c}
-void   foo__bar__baz_bah__free_unpacked
-                     (Foo__Bar__BazBah *message,
-                      ProtobufCAllocator *allocator);
-~~~
- *
- * - `get_packed_size()`. Calculates the length in bytes of the serialized
- *   representation of the message object.
- *
-~~~{.c}
-size_t foo__bar__baz_bah__get_packed_size
-                     (const Foo__Bar__BazBah   *message);
-~~~
- *
- * - `pack()`. Pack a message object into a preallocated buffer. Assumes that
- *   the buffer is large enough. (Use `get_packed_size()` first.)
- *
-~~~{.c}
-size_t foo__bar__baz_bah__pack
-                     (const Foo__Bar__BazBah   *message,
-                      uint8_t             *out);
-~~~
- *
- * - `pack_to_buffer()`. Packs a message into a "virtual buffer". This is an
- *   object which defines an "append bytes" callback to consume data as it is
- *   serialized.
- *
-~~~{.c}
-size_t foo__bar__baz_bah__pack_to_buffer
-                     (const Foo__Bar__BazBah   *message,
-                      ProtobufCBuffer     *buffer);
-~~~
- *
- * \page pack Packing and unpacking messages
- *
- * To pack a message, first compute the packed size of the message with
- * protobuf_c_message_get_packed_size(), then allocate a buffer of at least
- * that size, then call protobuf_c_message_pack().
- *
- * Alternatively, a message can be serialized without calculating the final size
- * first. Use the protobuf_c_message_pack_to_buffer() function and provide a
- * ProtobufCBuffer object which implements an "append" method that consumes
- * data.
- *
- * To unpack a message, call the protobuf_c_message_unpack() function. The
- * result can be cast to an object of the type that matches the descriptor for
- * the message.
- *
- * The result of unpacking a message should be freed with
- * protobuf_c_message_free_unpacked().
