PerlIO::Scalar - support module for in-memory IO.
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.
To install if, copy and paste the appropriate command in to your terminal.
perl -MCPAN -e shell
