This package overrides the implementation of these methods, not the semantics. .PP The default behavior is to allow either \s-1VMS\s0 or Unix syntax on input and to return \s-1VMS\s0 syntax on output, even when Unix syntax was given on input. .PP When used with a Perl of version 5.10 or greater and a \s-1CRTL\s0 possessing the relevant capabilities, override behavior depends on the \s-1CRTL\s0 features \&\f(CW\*(C`DECC$FILENAME_UNIX_REPORT\*(C'\fR and \f(CW\*(C`DECC$EFS_CHARSET\*(C'\fR. When the \&\f(CW\*(C`DECC$EFS_CHARSET\*(C'\fR feature is enabled and the input parameters are clearly in Unix syntax, the output will be in Unix syntax. If \&\f(CW\*(C`DECC$FILENAME_UNIX_REPORT\*(C'\fR is enabled and the output syntax cannot be determined from the input syntax, the output will be in Unix syntax. .IP "canonpath (override)" 4 .IX Item "canonpath (override)" Removes redundant portions of file specifications according to the syntax detected. .IP "catdir (override)" 4 .IX Item "catdir (override)" Concatenates a list of file specifications, and returns the result as a directory specification. No check is made for \*(L"impossible\*(R" cases (e.g. elements other than the first being absolute filespecs). .IP "catfile (override)" 4 .IX Item "catfile (override)" Concatenates a list of directory specifications with a filename specification to build a path. .IP "curdir (override)" 4 .IX Item "curdir (override)" Returns a string representation of the current directory: '[]' or '.' .IP "devnull (override)" 4 .IX Item "devnull (override)" Returns a string representation of the null device: '_NLA0:' or '/dev/null' .IP "rootdir (override)" 4 .IX Item "rootdir (override)" Returns a string representation of the root directory: 'SYS$DISK:[000000]' or '/' .IP "tmpdir (override)" 4 .IX Item "tmpdir (override)" Returns a string representation of the first writable directory from the following list or '' if none are writable: .Sp .Vb 3 \& /tmp if C is enabled. \& sys$scratch: \& $ENV{TMPDIR} .Ve .Sp Since perl 5.8.0, if running under taint mode, and if \f(CW$ENV\fR{\s-1TMPDIR\s0} is tainted, it is not used. .IP "updir (override)" 4 .IX Item "updir (override)" Returns a string representation of the parent directory: '[\-]' or '..' .IP "case_tolerant (override)" 4 .IX Item "case_tolerant (override)" \&\s-1VMS\s0 file specification syntax is case-tolerant. .IP "path (override)" 4 .IX Item "path (override)" Translate logical name \s-1DCL$PATH\s0 as a searchlist, rather than trying to \f(CW\*(C`split\*(C'\fR string value of \f(CW$ENV{\*(AqPATH\*(Aq}\fR. .IP "file_name_is_absolute (override)" 4 .IX Item "file_name_is_absolute (override)" Checks for \s-1VMS\s0 directory spec as well as Unix separators. .IP "splitpath (override)" 4 .IX Item "splitpath (override)" .Vb 2 \& ($volume,$directories,$file) = File::Spec\->splitpath( $path ); \& ($volume,$directories,$file) = File::Spec\->splitpath( $path, $no_file ); .Ve .Sp Passing a true value for \f(CW$no_file\fR indicates that the path being split only contains directory components, even on systems where you can usually (when not supporting a foreign syntax) tell the difference between directories and files at a glance. .IP "splitdir (override)" 4 .IX Item "splitdir (override)" Split a directory specification into the components. .IP "catpath (override)" 4 .IX Item "catpath (override)" Construct a complete filespec. .IP "abs2rel (override)" 4 .IX Item "abs2rel (override)" Attempt to convert a file specification to a relative specification. On a system with volumes, like \s-1VMS\s0, this may not be possible. .IP "rel2abs (override)" 4 .IX Item "rel2abs (override)" Return an absolute file specification from a relative one. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright (c) 2004 by the Perl 5 Porters.
