SYNOPSIS¶
#include <libexplain/tmpnam.h>
char *explain_tmpnam_or_die(char *pathname);
char *explain_tmpnam_on_error(char *pathname);
DESCRIPTION¶
The
explain_tmpnam_or_die function is used to call the

stderr,
obtained from the
explain_tmpnam(3) function, and then the process
terminates by calling exit(EXIT_FAILURE).
The
explain_tmpnam_on_error function is used to call the
tmpnam(3)
system call. On failure an explanation will be printed to
stderr,
obtained from the
explain_tmpnam(3) function, but still returns to the
caller.
- pathname
- The pathname, exactly as to be passed to the
tmpnam(3) system call.
RETURN VALUE¶
The
explain_tmpnam_or_die function only returns on success, see
tmpnam(3) for more information. On failure, prints an explanation and
exits, it does not return.
The
explain_tmpnam_on_error function always returns the value return by
the wrapped
tmpnam(3) system call.
EXAMPLE¶

explain_tmpnam_or_die function is intended to be used in a fashion
similar to the following example:
char *result = explain_tmpnam_or_die(pathname);
