explain_mktemp_or_die - make a unique temporary filename and report errors
#include <libexplain/mktemp.h>
char *explain_mktemp_or_die(char *pathname);
char *explain_mktemp_on_error(char *pathname);
The explain_mktemp_or_die function is used to call the mktemp(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_mktemp(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_mktemp_on_error function is used to call the mktemp(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_mktemp(3) function, but still returns to the caller.
The explain_mktemp_or_die function only returns on success, see mktemp(3) for more information. On failure, prints an explanation and exits, it does not return.
The explain_mktemp_on_error function always returns the value return by the wrapped mktemp(3) system call.
The explain_mktemp_or_die function is intended to be used in a fashion similar to the following example:
char *result = explain_mktemp_or_die(pathname);
