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 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);
