NAME
PerlIO::scalar - in-memory IO, scalar IOSYNOPSIS
my $scalar = ''; ... open my $fh, "<", \$scalar or die; open my $fh, ">", \$scalar or die; open my $fh, ">>", \$scalar or die;
or
my $scalar = ''; ... open my $fh, "<:scalar", \$scalar or die; open my $fh, ">:scalar", \$scalar or die; open my $fh, ">>:scalar", \$scalar or die;
DESCRIPTION
A filehandle is opened but the file operations are performed ``in-memory'' on a scalar variable. All the normal file operations can be performed on the handle. The scalar is considered a stream of bytes. Currently fileno($fh) returns -1.IMPLEMENTATION NOTE
"PerlIO::scalar" only exists to use XSLoader to load C code that provides support for treating a scalar as an ``in memory'' file. One does not need to explicitly "use PerlIO::scalar".Contenus ©2006-2024 Benjamin Poulain
