explain_mknod_or_die3

Create a special or ordinary file and report errors

Usage

#include <libexplain/mknod.h>

void explain_mknod_or_die(const char *pathname, mode_t mode, dev_t dev);
int explain_mknod_on_error(const char *pathname, mode_t mode, dev_t dev);

Overview

The explain_mknod_or_die function is used to call the mknod(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_mknod(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

The explain_mknod_on_error function is used to call the mknod(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_mknod(3) function, but still returns to the caller.

pathname

The pathname, exactly as to be passed to the mknod(2) system call.

mode

The mode, exactly as to be passed to the mknod(2) system call.

dev

The dev, exactly as to be passed to the mknod(2) system call.

Return value

The explain_mknod_or_die function only returns on success, see mknod(2) for more information. On failure, prints an explanation and exits, it does not return.

The explain_mknod_on_error function always returns the value return by the wrapped mknod(2) system call.

Examples

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

explain_mknod_or_die(pathname, mode, dev);
