Darwin accepts any template, as demonstrated here:
#include <stdio.h>
#include <unistd.h>
int
main(void)
{
char template[] = {'T', '-', 'A', 'A', 'A', 'A', 'A', 'A', '\0'};
char *res = mkdtemp(template);
puts(res ? res : "(null)");
perror("mkdtemp");
}
Outputs:
T-AAAAAA
mkdtemp: Undefined error: 0
This does not match prescribed POSIX behavior, but it is what it is.
* test-suite/tests/filesys.test (skip-on-darwin): New procedure.
("mkdtemp")["invalid template"]: Skip on Darwin.
