Description:
Memory mapped files for POSIX and Windows; profiling libraries
This library provides a wrapper to mmap(2) or MapViewOfFile, allowing files or devices to be lazily loaded into memory as strict or lazy ByteStrings, ForeignPtrs or plain Ptrs, using the virtual memory subsystem to do on-demand loading. Modifications are also supported. . This package provides a library for the Haskell programming language, compiled for profiling. See http://www.haskell.org/ for more information on Haskell.
