NAME
PerlIO::mmap - Memory mapped IOSYNOPSIS
open my $fh, '<:mmap', $filename;
DESCRIPTION
This layer does "read" and "write" operations by mmap()ing the file if possible, but falls back to the default behavior if not.IMPLEMENTATION NOTE
"PerlIO::mmap" only exists to use XSLoader to load C code that provides support for using memory mapped IO. One does not need to explicitly "use PerlIO::mmap;".| 2022-02-19 | perl v5.34.1 |
