SYNOPSIS    [Toc]    [Back]

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

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

DESCRIPTION    [Toc]    [Back]

     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    [Toc]    [Back]

     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    [Toc]    [Back]

     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.

			path prefix, or write permission is denied on the parent
 directory of the directory to be created.

     [ELOOP]		Too many symbolic links were encountered in translating
 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 contain
 the directory has been exhausted.

     [EDQUOT]		The user's quota of inodes on the file system on which
			the directory is being created has been exhausted.

     [EIO]		An I/O error occurred while making the directory entry
