| 28 | =head1 DESCRIPTION
|
|---|
| 29 |
|
|---|
| 30 | A filehandle is opened but the file operations are performed "in-memory"
|
|---|
| 31 | on a scalar variable. All the normal file operations can be performed
|
|---|
| 32 | on the handle. The scalar is considered a stream of bytes. Currently
|
|---|
| 33 | fileno($fh) returns C<undef>.
|
|---|
| 34 |
|
|---|
| 35 | =head1 IMPLEMENTATION NOTE
|
|---|
| 36 |
|
|---|
| 37 | C<PerlIO::scalar> only exists to use XSLoader to load C code that
|
|---|
| 38 | provides support for treating a scalar as an "in memory" file.
|
|---|
| 39 | One does not need to explicitly C<use PerlIO::scalar>.
