Hi
Did CBS win the obfuscated C contest yet?
I was just looking at a msan issue and then looked at this:
CHECK(FUNC_SEI(message_list)(ctx, rw, ¤t->message_list, 1));
#define CHECK(call) do { \
err = (call); \
if (err < 0) \
return err; \
} while (0)
#define FUNC_NAME2(rw, codec, name) cbs_ ## codec ## _ ## rw ## _ ## name
#define FUNC_NAME1(rw, codec, name) FUNC_NAME2(rw, codec, name)
#define FUNC_H264(name) FUNC_NAME1(READWRITE, h264, name)
#define FUNC_H265(name) FUNC_NAME1(READWRITE, h265, name)
#define FUNC_H266(name) FUNC_NAME1(READWRITE, h266, name)
#define FUNC_SEI(name) FUNC_NAME1(READWRITE, sei, name)
#define SEI_FUNC(name, args) \
static int FUNC(name) args; \
static int FUNC(name ## _internal)(CodedBitstreamContext *ctx, \
RWContext *rw, void *cur, \
SEIMessageState *state) \
{ \
return FUNC(name)(ctx, rw, cur, state); \
} \
static int FUNC(name) args
anyway, can we remove all preprocessor use from cbs ?
thx
