Macro Definition Documentation

av_assert0

#define av_assert0

(

cond

)

Value:

    do {                                           \
    if (!(cond)) {                                                      \
        av_log(NULL, AV_LOG_PANIC, "Assertion %s failed at %s:%d\n",    \
               AV_STRINGIFY(cond), __FILE__, __LINE__);                 \
        abort();                                                        \

} while (0)

assert() equivalent, that is always enabled.

Examples

mux.c, and transcode_aac.c.

av_assert1

#define av_assert1

(

cond

)

((void)0)

assert() equivalent, that does not lie in speed critical code.

These asserts() thus can be enabled without fearing speed loss.

av_assert2

#define av_assert2

(

cond

)

((void)0)

assert() equivalent, that does lie in speed critical code.

Definition at line 64 of file avassert.h.

av_assert2_fpu

#define av_assert2_fpu

(

)

((void)0)

Definition at line 65 of file avassert.h.

Function Documentation

av_assert0_fpu()

void av_assert0_fpu

(

void

)

Assert that floating point operations can be executed.

This will av_assert0() that the cpu is not in MMX state on X86
