Either -argument may be a string, a FileHandle reference or a FileHandle -glob. Obviously, if the first argument is a filehandle of some -sort, it will be read from, and if it is a file I<name> it will -be opened for reading. Likewise, the second argument will be -written to (and created if need be). - -B<Note that passing in -files as handles instead of names may lead to loss of information -on some operating systems; it is recommended that you use file -names whenever possible.> Files are opened in binary mode where -applicable. To get a consistent behaviour when copying from a -filehandle to a file, use C<binmode> on the filehandle. - -An optional third parameter can be used to specify the buffer -size used for copying. This is the number of bytes from the -first file, that wil be held in memory at any given time, before -being written to the second file. The default buffer size depends -upon the file, but will generally be the whole file (up to 2Mb), or -1k for filehandles that do not reference files (eg. sockets). - -You may use the syntax C<use File::Copy "cp"> to get at the -"cp" alias for this function. The syntax is I<exactly> the same. - -=item * - -The C<move> function also takes two parameters: the current name -and the intended name of the file to be moved. If the destination -already exists and is a directory, and the source is not a -directory, then the source file will be renamed into the directory -specified by the destination. - -If possible, move() will simply rename the file. Otherwise, it copies -the file to the new location and deletes the original. If an error occurs -during this copy-and-delete process, you may be left with a (possibly partial) -copy of the file under the destination name. - -You may use the "mv" alias for this function in the same way that -you may use the "cp" alias for C<copy>. - -=back - -File::Copy also provides the C<syscopy> routine, which copies the -file specified in the first parameter to the file specified in the -second parameter, preserving OS-specific attributes and file -structure. For Unix systems, this is equivalent to the simple -C<copy> routine. For VMS systems, this calls the C<rmscopy> -routine (see below). For OS/2 systems, this calls the C<syscopy> -XSUB directly. For Win32 systems, this calls C<Win32::CopyFile>. - -=head2 Special behaviour if C<syscopy> is defined (OS/2, VMS and Win32) - -If both arguments to C<copy> are not file handles, -then C<copy> will perform a "system copy" of -the input file to a new output file, in order to preserve file -attributes, indexed file structure, I<etc.> The buffer size -parameter is ignored. If either argument to C<copy> is a -handle to an opened file, then data is copied using Perl -operators, and no effort is made to preserve file attributes -or record structure. - -The system copy routine may also be called directly under VMS and OS/2 -as C<File::Copy::syscopy> (or under VMS as C<File::Copy::rmscopy>, which -is the routine that does the actual work for syscopy). - -=over 4 - -=item rmscopy($from,$to[,$date_flag]) - -The first and second arguments may be strings, typeglobs, typeglob -references, or objects inheriting from IO::Handle; -they are used in all cases to obtain the -I<filespec> of the input and output files, respectively. The -name and type of the input file are used as defaults for the -output file, if necessary. - -A new version of the output file is always created, which -inherits the structure and RMS attributes of the input file, -except for owner and protections (and possibly timestamps; -see below). All data from the input file is copied to the -output file; if either of the first two parameters to C<rmscopy> -is a file handle, its position is unchanged. (Note that this -means a file handle pointing to the output file will be -associated with an old version of that file after C<rmscopy> -returns, not the newly created version.) - -The third parameter is an integer flag, which tells C<rmscopy> -how to handle timestamps. If it is E<lt> 0, none of the input file's -timestamps are propagated to the output file. If it is E<gt> 0, then -it is interpreted as a bitmask: if bit 0 (the LSB) is set, then -timestamps other than the revision date are propagated; if bit 1 -is set, the revision date is propagated. If the third parameter -to C<rmscopy> is 0, then it behaves much like the DCL COPY command: -if the name or type of the output file was explicitly specified, -then no timestamps are propagated, but if they were taken implicitly -from the input filespec, then all timestamps other than the -revision date are propagated. If this parameter is not supplied, -it defaults to 0. - -Like C<copy>, C<rmscopy> returns 1 on success. If an error occurs, -it sets C<$!>, deletes the output file, and returns 0. - -=back - -=head1 RETURN - -All functions return 1 on success, 0 on failure. -$! will be set if an error was encountered. - -=head1 AUTHOR - -File::Copy was written by Aaron Sherman I<E<lt>ajs@ajs.comE<gt>> in 1995, -and updated by Charles Bailey I<E<lt>bailey@newman.upenn.eduE<gt>> in 1996. - -=cut - diff --git a/contrib/perl5/lib/File/DosGlob.pm b/contrib/perl5/lib/File/DosGlob.pm deleted file mode 100644 index d7dea7b..0000000 --- a/contrib/perl5/lib/File/DosGlob.pm +++ /dev/null @@ -1,254 +0,0 @@ -#!perl -w - -# -# Documentation at the __END__ -# - -package File::DosGlob; - -sub doglob { - my $cond = shift; - my @retval = (); - #print "doglob: ", join('|', @_), "\n"; - OUTER: - for my $arg (@_) { - local $_ = $arg; - my @matched = (); - my @globdirs = (); - my $head = '.'; - my $sepchr = '/'; - next OUTER unless defined $_ and $_ ne ''; - # if arg is within quotes strip em and do no globbing - if (/^"(.*)"\z/s) { - $_ = $1; - if ($cond eq 'd') { push(@retval, $_) if -d $_ } - else { push(@retval, $_) if -e $_ } - next OUTER; - } - # wildcards with a drive prefix such as h:*.pm must be changed - # to h:./*.pm to expand correctly - if (m|^([A-Za-z]:)[^/\\]|s) { - substr($_,0,2) = $1 .

(Note that this still -overrides your stat() and lstat() functions.) Access these fields as -variables named with a preceding C<st_> in front their method names. -Thus, C<$stat_obj-E<gt>dev()> corresponds to $st_dev if you import -the fields. - -To access this functionality without the core overrides, -pass the C<use> an empty import list, and then access -function functions with their full qualified names. -On the other hand, the built-ins are still available -via the C<CORE::> pseudo-package. - -=head1 NOTE - -While this class is currently implemented using the Class::Struct -module to build a struct-like class, you shouldn't rely upon this. - -=head1 AUTHOR - -Tom Christiansen |
