.SH Name
rmdir \- remove a directory file
.SH Syntax
.nf
.B rmdir(path)
.B char *path;
.fi
.SH Description
.NXR "rmdir system call"
.NXR "directory" "removing"
The
.PN rmdir
system call
removes a directory file
whose name is given by
.I path.
The directory must not have any entries other
than dot (.) and dot-dot (..).
.PP
If one or more processes have the directory open when the last
link is removed, the dot and dot-dot entries, if present, are
removed before 
.PN rmdir() 
returns and no new entries may be created
in the directory.  The directory, however, is not removed until
all references to the directory have been closed.
.SH Return Values
A zero (0) is returned if the remove succeeds; otherwise, a \-1 is
returned, and an error code is stored in the global location \fIerrno\fP\|.
