NAME¶
explain_mknod_or_die - create a special or ordinary file and report errors
SYNOPSIS¶
#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);
DESCRIPTION¶
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.
EXAMPLE¶
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);
