MKNOD(2) MKNOD(2) NAME mknod - make a directory or a special file SYNOPSIS mknod(name, mode, addr) char *name; DESCRIPTION Mknod creates a new file whose name is the null-terminated string pointed to by name. The mode of the new file (includ- ing directory and special file bits) is initialized from mode. (The protection part of the mode is modified by the process's mode mask; see umask(2)). The first block pointer of the i-node is initialized from addr. For ordinary files and directories addr is normally zero. In the case of a special file, addr specifies which special file. Mknod may be invoked only by the super-user. SEE ALSO mkdir(1), mknod(1), filsys(5) DIAGNOSTICS Zero is returned if the file has been made; -1 if the file already exists or if the user is not the super-user.
