# [NAME](#NAME)

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

# [SYNOPSIS](#SYNOPSIS)

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

# [DESCRIPTION](#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](#canonpath)

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

[file\_name\_is\_absolute](#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)](#tmpdir)

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](#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
