.SH NAME
mkdirp, rmdirp \- create or remove directories in a path
.SH SYNOPSIS
.LP
.nf
cc [ \fIflag\fR ... ] \fIfile\fR ... \fB-lgen\fR [ \fIlibrary\fR ... ]
#include <libgen.h>

\fBint\fR \fBmkdirp\fR(\fBconst char *\fR\fIpath\fR, \fBmode_t\fR \fImode\fR);
.fi

.LP
.nf
\fBint\fR \fBrmdirp\fR(\fBchar *\fR\fIdir\fR, \fBchar *\fR\fIdir1\fR);
.fi

.SH DESCRIPTION
.sp
.LP
The \fBmkdirp()\fR function creates all the missing directories in \fIpath\fR
with \fImode\fR. See \fBchmod\fR(2) for the values of \fImode\fR.
.sp
.LP
The \fBrmdirp()\fR function removes directories in path \fIdir\fR. This removal
begins at the end of the path and moves backward toward the root as far as
possible. If an error occurs, the remaining path is stored in \fIdir1\fR.
.SH RETURN VALUES
.sp
.LP
If \fIpath\fR already exists or if a needed directory cannot be created,
\fBmkdirp()\fR returns \fB\(mi1\fR and sets \fBerrno\fR to one of the error
values listed for \fBmkdir\fR(2). It returns zero if all the directories are
created.
.sp
.LP
The \fBrmdirp()\fR function returns \fB0\fR if it is able to remove every
directory in the path. It returns \fB\(mi2\fR if a ``\fB\&.\fR'' or
``\fB\&..\fR'' is in the path and \fB\(mi3\fR if an attempt is made to remove
the current directory. Otherwise it returns \fB\(mi1\fR\&.
.SH EXAMPLES
.LP
\fBExample 1 \fRExample of creating scratch directories.
.sp
.LP
The following example creates scratch directories.

.sp
.in +2
.nf
/* create scratch directories */
if(mkdirp("/tmp/sub1/sub2/sub3", 0755) == \(mi1) {
	fprintf(stderr, "cannot create directory");
	exit(1);
}
chdir("/tmp/sub1/sub2/sub3");

for the string.
