# File::Spec::Cygwin(3p)

methods for Cygwin file specs

## NAME

File::Spec::Cygwin - methods for Cygwin file specs

## SYNOPSIS

```
 require File::Spec::Cygwin; # Done internally by File::Spec if needed
```

## DESCRIPTION

See File::Spec and File::Spec::Unix.  This package overrides the implementation of these methods, not the semantics.

This module is still in beta.  Cygwin-knowledgeable folks are invited to offer patches and suggestions.

- canonpath

  Any `"\"` (backslashes) are converted to `"/"` (forward slashes), and then File::Spec::Unix **canonpath()** is called on the result.

- file\_name\_is\_absolute

  True is returned if the file name begins with `"drive_letter:"`, and if not, File::Spec::Unix **file\_name\_is\_absolute()** is called.

- tmpdir (override)

  Returns a string representation of the first existing directory from the following list:

  ```
      $ENV{TMPDIR}
      /tmp
      $ENV{'TMP'}
      $ENV{'TEMP'}
      C:/temp
  ```

  If running under taint mode, and if the environment variables are tainted, they are not used.

- case\_tolerant

  Override Unix. Cygwin case-tolerance depends on managed mount settings and as with MsWin32 on **GetVolumeInformation()** `$ouFsFlags` == FS\_CASE\_SENSITIVE, indicating the case significance when comparing file specifications. Default: 1
