DESCRIPTION

A simplistic interface for reading memory mapped files

FEATURES/PROBLEMS

• mmap a file. Read data from it. Close it when you’re done. More fun than the “ball in a cup” game.
  
• it ONLY supports reading mmap'ed files, not writing to the mmap'ed region

SYNOPSIS

>> fw = SimpleMmap::FileWindow.open("path/to/large/file")
>> fw[23467, 200] #=> data between byte 23467 and the next 200 bytes  
# works with the same semantics as Array#[] (eg. fw[10..14] and fw[10...14])  
>> fw.close # you MUST close the FileWindow after you're done (HAHA no blocks for you yet!)

REQUIREMENTS

• A mmap() capable platform.

INSTALL

$ gem install simple_mmap
# If you have ruby 1.9+ built with executables having a program-suffix:  
$ env rake=rake1.9 gem install simple_mmap
