Something is invalid with these macros.
Takes localtime_r for example... Both the GNU and standard cannot be compiled...
Is it just me?
#include <time.h>
#define localtime_r_1(_Time, _Tm) ({ struct tm *___tmp_tm =
\
localtime((_Time)); \
if (___tmp_tm) \
*(_Tm) = *___tmp_tm; \
else *(_Tm) = 0; \
___tmp_tm; })
#define localtime_r_2(_Time, _Tm) (localtime ((_Time)) ? *(_Tm) =
*localtime ((_Time),(_Tm)) : 0)
int main(void) {
time_t t1;
struct tm tm1;
localtime_r_1(&t1, &tm1);
localtime_r_2(&t1, &tm1);
}
$ x86_64-w64-mingw32-gcc -pedantic /tmp/time.c
/tmp/time.c: In function ‘main’:
