NAME¶
explain_tmpfile_or_die - create a temporary file and report errors
SYNOPSIS¶
#include <libexplain/tmpfile.h>
FILE *explain_tmpfile_or_die(void);
FILE *explain_tmpfile_on_error(void);
DESCRIPTION¶
The
explain_tmpfile_or_die function is used to call the
tmpfile(3)
system call. On failure an explanation will be printed to
stderr,
obtained from the
explain_tmpfile(3) function, and then the process
terminates by calling exit(EXIT_FAILURE).
The
explain_tmpfile_on_error function is used to call the
tmpfile(3) system call. On failure an explanation will be printed to
stderr, obtained from the
explain_tmpfile(3) function, but still
returns to the caller.
RETURN VALUE¶
The
explain_tmpfile_or_die function only returns on success, see
tmpfile(3) for more information. On failure, prints an explanation and
exits, it does not return.
The
explain_tmpfile_on_error function always returns the value return by
the wrapped
tmpfile(3) system call.
EXAMPLE¶
The
explain_tmpfile_or_die function is intended to be used in a fashion
similar to the following example:
FILE *result = explain_tmpfile_or_die();
