$PERLDB

C-style Logical Or Binary "||" performs a short-circuit logical OR operation. That is, if the left operand is true, the right operand is not even evaluated. Scalar or list context propagates down to the right operand if it is evaluated.

NAME SYNOPSIS DESCRIPTION USAGE FUNCTIONS EXAMPLE AUTHOR NAME ExtUtils::Packlist - manage .packlist files SYNOPSIS use ExtUtils::Packlist; my ($pl) = ExtUtils::Packlist->new('.packlist'); $pl->read('/an/old/.packlist'); my @missing_files = $pl->validate(); $pl->write('/a/new/.packlist'); $pl->{'/some/file/name'}++; or $pl->{'/some/other/file/name'} = { type => 'file', from => '/some/file' }; DESCRIPTION ExtUtils::Packlist provide

truncate FILEHANDLE,LENGTH truncate EXPR,LENGTH Truncates the file opened on FILEHANDLE, or named by EXPR, to the specified length. Raises an exception if truncate isn't implemented on your system. Returns true if successful, undef on error. The behavior is undefined if LENGTH is greater than the length of the file. The position in the file of FILEHANDLE is left unchanged. You may want to call seek before writing to the file. Portability issues: truncate in perlport.

sysopen FILEHANDLE,FILENAME,MODE sysopen FILEHANDLE,FILENAME,MODE,PERMS Opens the file whose filename is given by FILENAME, and associates it with FILEHANDLE. If FILEHANDLE is an expression, its value is used as the real filehandle wanted; an undefined scalar will be suitably autovivified. This function calls the underlying operating system's open(2) function with the parameters FILENAME, MODE, and PERMS. The possible values and flag bits of the MODE parameter are system-dependent; they are ava

telldir DIRHANDLE Returns the current position of the readdir routines on DIRHANDLE. Value may be given to seekdir to access a particular location in a directory. telldir has the same caveats about possible directory compaction as the corresponding system library routine.
