Parameters

pSrc

Pointer to the input buffer holding the compressed data.

srcLen

Length of the compressed data buffer.

pState

Pointer to the ZFP decompression structure.

Description

This function initializes the ZFP decompression structure. Its size must be calculated by calling the function DecodeZfpGetStateSize beforehand.
