The following is an implementation of the Standard C99 version of <assert.h>:
/* assert.h header */ #undef assert #ifdef NDEBUG #define assert(_Ignore) ((void)0) #else void_Assertfail(char*,char*,int,char*); #define assert(_Test) ((_Test)?((void)0):_Assertfail(#_Test,__FILE__,__LINE__,__func__)) #endif /* END OF FILE */
/* xassertfail.c -- _Assertfail function */ #include<stdlib.h> #include<stdio.h> #include<assert.h> void _Assertfail(char*test,char*filename,intline_number,char*function_name) { fprintf(stderr,"Assertion failed: %s, function %s, file %s, line %d.", test,function_name,filename,line_number); abort(); } /* END OF FILE */
