Detailed Description

ZLIB file inflation utility library.

Author:

D.L. Wood

This library provides a slightly higher level interface to the ZLIB inflation utility than does the inflate() interface. One advantage is that the user does not need to worry about the details of the ZLIB stream structure. Another goal of this library is to minimize the amount of temporary buffer storage required to inflate large files. This is particulary important when inflating one file into another. In cases where a file handle is needed as a function parameter, the user is resposible for opening (or creating) the handle before calling the function and for closing the handle after completion.

When inflating file data, the functions in this library expect to find a 32-bit, big-endian word to the head of the input stream. This word contains the size in bytes of the original file. Following the 32-bit size word is the standard ZLIB compressed data stream. This format is produced by the zlib_file_compress library functions.

On VxWorks platforms, the PBS/MBA facility must be initialized.
