NAME

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

SYNOPSIS

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

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

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.
