Detailed Description

simple assert() macros that are a bit more flexible than ISO C assert().

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: muxing.c, and transcode_aac.c.

Definition at line 37 of file avassert.h.

◆ 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.

Definition at line 53 of file avassert.h.

◆ 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

Something went really wrong and we will crash now.
