# OpenBSD::MkTemp(3p)

Perl access to mkstemps() and mkdtemp()

## NAME

OpenBSD::MkTemp - Perl access to mkstemps() and mkdtemp()

## SYNOPSIS

```
  use OpenBSD::MkTemp;
  my($fh, $file) = mkstemp("/tmp/fooXXXXXXXXXX");
  use OpenBSD::MkTemp qw(mkdtemp mkstemps);
  my $dir_name = mkdtemp("/tmp/dirXXXXXXXXXX");
  my ($fh, $file) = mkstemps("/tmp/fileXXXXXXXXXX", ".tmp");
```

## DESCRIPTION

This module provides routines for creating files and directories with guaranteed unique names, using the C **mkstemps()** and **mkdtemp()** routines.

**mkstemp()** and **mkstemps()** must be called with a template argument that is writable, so that they can update it with the path of the generated file. They return normal perl IO handles.

**mkdtemp()** simply takes the template and returns the path of the newly created directory.

### EXPORT

```
  $fh = mkstemp($template)
```

### Exportable functions

```
  $fh = mkstemps($template, $suffix_len)
  $dir = mkdtemp($template);
```
