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);
