## ZZIP Programmers Interface

The complete API description.

The zzip library was orginally developped by Tomi Ollila as a set of zip decoder routines. Guido Draheim did pick it up and wrapped them under a call synopsis matching their posix api calls. Therefore `zzip_open()` has the same synopsis as `open(2)` but it can open zipped files. Later the distinction was made between magic wrappers and apis for direct access to zip archives and the files contained in the archive.

These (three) functional apis have little helper functions alongside including those to get the posix filehandle out of a zzip handle and to get some attributes about the data handle represented by a zzip handle. Plus checking for error codes that may have been generated from internal checks.

Basics
  Magic Wrappers, Zip Archive Dir access, Zipped File access
Extras
  ext/io init, StdC calls, Error defs, ReOpen, FileStat
