- =head1 NAME
-
- FileHandle - supply object methods for filehandles
-
- cacheout - keep more files open than the system permits
-
- =head1 SYNOPSIS
-
- use FileHandle;
- autoflush STDOUT 1;
-
- cacheout($path);
- print $path @data;
-
- =head1 DESCRIPTION
-
- See L<perlvar> for complete descriptions of each of the following supported C<FileHandle>
- methods:
-
- print
- autoflush
- output_field_separator
- output_record_separator
- input_record_separator
- input_line_number
- format_page_number
- format_lines_per_page
- format_lines_left
- format_name
- format_top_name
- format_line_break_characters
- format_formfeed
-
- The cacheout() function will make sure that there's a filehandle
- open for writing available as the pathname you give it. It automatically
- closes and re-opens files if you exceed your system file descriptor maximum.
-
- =head1 BUGS
-
- F<sys/param.h> lies with its C<NOFILE> define on some systems,
- so you may have to set $cacheout::maxopen yourself.
-
- Due to backwards compatibility, all filehandles resemble objects
- of class C<FileHandle>, or actually classes derived from that class.
- They actually aren't. Which means you can't derive your own
- class from C<FileHandle> and inherit those methods.
