# Makefile for rmdir(1) and rmdir(3) v1.0
#
# Devin Reade, <gdr@myrias.ab.ca> November 1994.
#
# Define:
# SHELL_COMD if you want to compile the shell command version.
# In this case, do a 'make rmdir'. If you want just
# the rmdir(3) library routine, don't define
# SHELL_COMD and do a 'make rmdir.o'
#
# CHECK_STACK if you want to determine stack usage. If you select
# This option, you must also specify the stack library,
# nominally -l/usr/lib/stack.

will have an exit status of zero on success, -1 on failure.

.SH BUGS
It is possible to delete the current directory of

.TH RMDIR 2 "System Calls" "28 November 1994" "Version 1.0"
.SH NAME
rmdir \- remove (delete) a directory
.SH SYNOPSIS
int \fBrmdir\fR (const char *\fIpath\fR);
.SH DESCRIPTION
.BR rmdir
will remove the directory named by
.I path
if the directory is empty, if it is not a mount point, and if the calling
process has write permission in the parent directory. The directory is
considered empty when it contains only
.B .
and
.B ..
entries.
.SH "RETURN VALUE"
0 if successful, -1 and sets
.B errno
otherwise.
.SH BUGS
Since
.BR rmdir
is not yet implemented as a system call but as a library call, it is
possible to delete a directory which is being used by a process, including
that of
.BR rmdir .
.SH AUTHOR
Devin Reade, <gdr@myrias.ab.ca>
.SH "SEE ALSO"
.BR mkdir (2),

/*
* rmdir - remove directory
*
* A quick and dirty utility for Gno. This will delete all empty
* directories given as arguments. It will skip non-directory files
* directories that aren't empty.
* ChangeLog:
* v1.1 - incorporated into GNO base distribution
* - added -p flag for POSIX conformance
* - moved rmdir(2) implementation to libc
* v1.0 - initial revision
*
* If you don't compile with #define SHELL_COMD, then you just get the
* rmdir(2) system call.
*
* Version 1.0 by Devin Reade <gdr@myrias.ab.ca>
* Version 1.1 by Devin Reade <gdr@myrias.ab.ca>
