.SH NAME
|
|
mkdtemp \- create a unique temporary directory
|
|
.SH SYNOPSIS
|
|
.nf
|
|
.B #include <stdlib.h>
|
|
.sp
|
|
.BI "char *mkdtemp(char *" template );
|
|
.fi
|
|
.SH DESCRIPTION
|
|
The \fBmkdtemp()\fP function generates a uniquely-named temporary
|
|
directory from \fItemplate\fP. The last six characters of \fItemplate\fP
|
|
must be XXXXXX and these are replaced with a string that makes the
|
|
.\" FIXME: were the permissions 0700 in all glibc versions ?
|
|
directory name unique. The directory is then created with
|
|
permissions 0700.
|
|
Since it will be modified,
|
|
.I template
|
|
must not be a string constant, but should be declared as a character array.
|
|
.SH "RETURN VALUE"
|
|
The \fBmkdtemp()\fP function returns a pointer to the modified template
|
|
string on success, and \fBNULL\fP on failure, in which case
|
|
.IR errno
|
|
is set appropriately.
|
|
.SH ERRORS
|
|
.TP
|
|
.B EINVAL
|
|
The last six characters of \fItemplate\fP were not XXXXXX.
|
|
Now \fItemplate\fP is unchanged.
|
|
|
|
.TP
|
|
Also see \fBmkdir(2)\fP for other possible values for \fIerrno\fP.
|
|
|
|
