explain_mkostemp_or_die - create a unique temporary file and report errors

#include <libexplain/mkostemp.h>

int explain_mkostemp_or_die(char *templat, int flags);
int explain_mkostemp_on_error(char *templat, int flags);

The explain_mkostemp_or_die function is used to call the mkostemp(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_mkostemp(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

The explain_mkostemp_on_error function is used to call the mkostemp(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_mkostemp(3) function, but still returns to the caller.

The template, exactly as to be passed to the mkostemp(3) system call.
The flags, exactly as to be passed to the mkostemp(3) system call.

The explain_mkostemp_or_die function only returns on success, see mkostemp(3) for more information. On failure, prints an explanation and exits, it does not return.

The explain_mkostemp_on_error function always returns the value return by the wrapped mkostemp(3) system call.

The explain_mkostemp_or_die function is intended to be used in a fashion similar to the following example:

int result = explain_mkostemp_or_die(templat, flags);

mkostemp(3)
create a unique temporary file
explain_mkostemp(3)
explain mkostemp(3) errors
exit(2)
terminate the calling process
