open( $fh, "<:encoding(iso-8859-7)", $pathname );
-=item ":Scalar"
+=item ":scalar"
Provides support for reading data from and writing data to a scalar.
- open( $fh, ":Scalar", \$scalar );
+ open( $fh, "+<:scalar", \$scalar );
When a handle is so opened, then reads get bytes from the string value
of I<$scalar>, and writes change the value. In both cases the position
in I<$scalar> starts as zero but can be altered via C<seek>, and
determined via C<tell>.
-=item ":Via"
+Please note that this layer is implied when calling open() thus:
+
+ open( $fh, "+<", \$scalar );
+
+=item ":via"
Provided to allow layers to be implemented as Perl code. For instance:
- use PerlIO::Via::StripHTML;
- open( my $fh, ">:Via(StripHTML)", "index.html" );
+ use PerlIO::via::StripHTML;
+ open( my $fh, "<:via(StripHTML)", "index.html" );
