.IX Title "File::Spec::OS2 3"
.TH File::Spec::OS2 3 "2002-06-01" "perl v5.8.0" "Perl Programmers Reference Guide"
.RE
.IP "canonpath"
.IX Item "canonpath"
No physical check on the filesystem, but a logical cleanup of a
path. On \s-1UNIX\s0 eliminated successive slashes and successive \*(L"/.\*(R".
.RE
.IP "splitpath"
.IX Item "splitpath"
.Vb 2
\&    ($volume,$directories,$file) = File::Spec->splitpath( $path );
\&    ($volume,$directories,$file) = File::Spec->splitpath( $path, $no_file );
.Ve
.PP
Splits a path in to volume, directory, and filename portions. Assumes that 
the last file is a path unless the path ends in '/', '/.', '/..'
or \f(CW$no_file\fR is true.  On Win32 this means that \f(CW$no_file\fR true makes this return 
( \f(CW$volume\fR, \f(CW$path\fR, undef ).
.PP
Separators accepted are \e and /.
.PP
Volumes can be drive letters or \s-1UNC\s0 sharenames (\e\eserver\eshare).
.PP
The results can be passed to \*(L"catpath\*(R" to get back a path equivalent to
(usually identical to) the original path.
.RE
.IP "splitdir"
.IX Item "splitdir"
The opposite of \fIcatdir()\fR.
.PP
.Vb 1
\&    @dirs = File::Spec->splitdir( $directories );
.Ve
.PP
$directories must be only the directory portion of the path on systems 
that have the concept of a volume or that have path syntax that differentiates
files from directories.
.PP
Unlike just splitting the directories on the separator, leading empty and 
trailing directory entries can be returned, because these are significant
on some OSs. So,
.PP
.Vb 1
\&    File::Spec->splitdir( "/a/b//c/" );
.Ve
.PP
Yields:
.PP
.Vb 1
\&    ( '', 'a', 'b', '', 'c', '' )
.Ve
.RE
.IP "catpath"
.IX Item "catpath"
Takes volume, directory and file portions and returns an entire path. Under
Unix, \f(CW$volume\fR is ignored, and this is just like \fIcatfile()\fR. On other OSs,
the \f(CW$volume\fR become significant.
.SH "NAME"
File::Spec::OS2 \- methods for OS/2 file specs
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\& require File::Spec::OS2; # Done internally by File::Spec if needed
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
See File::Spec::Unix for a documentation of the methods provided
there. This package overrides the implementation of these methods, not
the semantics.
