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 (including 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.
