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".

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.
