AnyData::Storage::File(3pm) User Contributed Perl Documentation AnyData::Storage::File(3pm) NAME
AnyData::Storage::File -- manipulate files with rich warnings DESCRIPTION
Opens, reads from, writes to, creates and destroys files with numerous options for error handling, flocking, binmode, etc. The simplest form is the equivalent of my $f = AnyData::Storage::File->new(dirs=>@dirs,flock=>1); my $str1 = $f->adSlurp($file); for( @dirs ) { open(IN,$file) or die $!; } sub slurp { local *IN; local $/ = undef; } But, depending on how you set the default behaviour SYNOPSIS
use AnyData; my $f = AnyData::Storage::File->new; $f->set('binmode',1|0); $f->set('PrintError',1|0); $f->set('RaiseError',1|0); $f->set('Trace',1|0); $f->set('f_dir',$dir|$dir_array) < input, fail if doesn't exist > output, truncate if exists, create if doesn't >> append, create if doesn't exist +< read/write, fail if doesn't exist r = < r+ = new() my $f = AnyData::Storage::File->new; or my $f = AnyData::Storage::File->new( %flags ); %flags is a hash which can contain any or all of: f_dir => $directory, # defaults to './' ( binmode => $binmode, # defaults to 0 (doesn't binmode files) printError => $warnings, # defaults to 1 (print warning on errors) open_local_file( $fname, $mode ); Mode is one of a = append open for reading & writing, create if doesn't exist r = read open for reading, fail if doesn't exist u = open open for reading & writing, fail if doesn't exist c = create open for reading & writing, fail if it already exists o = overwrite open for reading & writing, overwrite if it already exists Additionally, all modes fail if the file can't be opened. On systems that support flock, 'r' fails if a shared lock can not be obtained; the other modes fail if an exclusive lock can't be obtained. perl v5.10.1 2004-08-17 AnyData::Storage::File(3pm)
