NAME

     mkdir -- make a directory file

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <sys/types.h>
     #include <sys/stat.h>

     int
     mkdir(const char *path, mode_t mode);

DESCRIPTION

     The directory path is created with the access permissions specified by
     mode and restricted by the umask(2) of the calling process.

     The directory's owner ID is set to the process's effective user ID.  The
     directory's group ID is set to that of the parent directory in which it
     is created.

RETURN VALUES

     The mkdir() function returns the value 0 if successful; otherwise the
     value -1 is returned and the global variable errno is set to indicate the
     error.

ERRORS

     The mkdir() system call will fail and no directory will be created if:

     [ENOTDIR]		A component of the path prefix is not a directory.

     [ENAMETOOLONG]	A component of a pathname exceeded 255 characters, or
			an entire path name exceeded 1023 characters.

     [ENOENT]		A component of the path prefix does not exist.

     [EACCES]		Search permission is denied for a component of the
			path prefix, or write permission is denied on the par-
			ent directory of the directory to be created.

     [ELOOP]		Too many symbolic links were encountered in translat-
			ing the pathname.

     [EROFS]		The named file resides on a read-only file system.

     [EEXIST]		The named file exists.

     [ENOSPC]		The new directory cannot be created because there is
			no space left on the file system that will contain the
			directory.

     [ENOSPC]		There are no free inodes on the file system on which
			the directory is being created.

     [EDQUOT]		The new directory cannot be created because the user's
			quota of disk blocks on the file system that will con-
			tain the directory has been exhausted.
			the file system.

     [EFAULT]		The path argument points outside the process's allo-
			cated address space.
