.SH DESCRIPTION
|
|
The
|
|
.BR mkdtemp ()
|
|
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
|
|
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
|
|
.BR mkdtemp ()
|
|
function returns a pointer to the modified template
|
|
string on success, and NULL on failure, in which case
|
|
.I errno
|
|
is set appropriately.
|
|
.SH ERRORS
|
|
.TP
|
|
.B EINVAL
|
|
The last six characters of \fItemplate\fP were not XXXXXX.
|
|
Now \fItemplate\fP is unchanged.
|
|

|
|
Also see
|
|

|
