NAME

6       PerlIO::scalar - in-memory IO, scalar IO
7

SYNOPSIS

9          my $scalar = '';
10          ...
11          open my $fh, "<",  \$scalar or die;
12          open my $fh, ">",  \$scalar or die;
13          open my $fh, ">>", \$scalar or die;
14
15       or
16
17          my $scalar = '';
18          ...
19          open my $fh, "<:scalar",  \$scalar or die;
20          open my $fh, ">:scalar",  \$scalar or die;
21          open my $fh, ">>:scalar", \$scalar or die;

DESCRIPTION

24       A filehandle is opened but the file operations are performed "in-
25       memory" on a scalar variable.  All the normal file operations can be
26       performed on the handle. The scalar is considered a stream of bytes.
27       Currently fileno($fh) returns -1.
28

IMPLEMENTATION NOTE

30       "PerlIO::scalar" only exists to use XSLoader to load C code that
31       provides support for treating a scalar as an "in memory" file.  One
32       does not need to explicitly "use PerlIO::scalar".
