Purely from memory, it is POSIX, though I would use STDOUT_FILENO
or fileno(stdout).
OK. I see I wasn't clear about what i was asking.
Here is the question rephrased:
Will I get the exact same stream handle every time I fdopen file dscriptor 1?
For example, does the following *guranteed* to work?
#include <stdio.h> #include <string.h>
int main(void) {
printf("stdout: %lx\n", stdout);
fclose(stdout);
if((FILE *)fdopen(1,"w") != stdout)
printf("1: %s\n", strerror);return 0; }
It does work in the specific example, btw.
