PerlIO::scalar

NAME

PerlIO::scalar - support module for in-memory IO.

SYNOPSIS

  1. open($fh,"<",\$scalar);
  2. open($fh,">",\$scalar);

or

  1. open($fh,"<:scalar",\$scalar);
  2. open($fh,">:scalar",\$scalar);

DESCRIPTION

PerlIO::scalar only exists to use XSLoader to load C code that provides support for treating a scalar as an "in memory" file.

All normal file operations can be performed on the handle. The scalar is considered a stream of bytes. Currently fileno($fh) returns undef.
