Detailed Description

Macros and constants used to manipulate the base "classes" generated by protobuf-c. They also define limits and check correctness.

Macro Definition Documentation

MAX_UINT64_ENCODED_SIZE

#define MAX_UINT64_ENCODED_SIZE   10

The maximum length of a 64-bit integer in varint encoding.

STRUCT_MEMBER

#define STRUCT_MEMBER	(		member_type,
			struct_p,
			struct_offset
	)		(*(member_type *) STRUCT_MEMBER_P((struct_p), (struct_offset)))

Return field in a ProtobufCMessage based on offset.

Take a pointer to a ProtobufCMessage and find the field at the offset. Cast it to the passed type.

STRUCT_MEMBER_P

#define STRUCT_MEMBER_P	(		struct_p,
			struct_offset
	)		((void *) ((uint8_t *) (struct_p) + (struct_offset)))

Internal ProtobufCMessage manipulation macro.

Base macro for manipulating a ProtobufCMessage. Used by STRUCT_MEMBER() and STRUCT_MEMBER_PTR().

STRUCT_MEMBER_PTR

#define STRUCT_MEMBER_PTR	(		member_type,
			struct_p,
			struct_offset
	)		((member_type *) STRUCT_MEMBER_P((struct_p), (struct_offset)))

Return field in a ProtobufCMessage based on offset.

Take a pointer to a ProtobufCMessage and find the field at the offset. Cast it to a pointer to the passed type.
