mknod

Syntax

#include <sys/stat.h> int mknod(const char *path, mode_t mode, dev_t dev);

Description

This function is provided to assist in porting from Unix. If mode specifies a regular file, mknod creates a file using path as its name. If mode specifies a character device, and if the device whose name is given by path exists and its device specification as returned by stat or fstat is equal to dev, mknod returns -1 and sets errno to EEXIST. In all other cases, -1 is returned errno is set to EACCES.

The argument dev is ignored if mode does not specify a character device.

Return Value

Zero on success, -1 on failure.
