Parameters

ppSrc

Double pointer to the source buffer.

pSrcLen

Pointer to the length of the source buffer, after decoding - pointer to the size of the remaining data.

pDst

Pointer to the destination buffer.

pDstLen

Pointer to the length of the destination buffer, after decoding - pointer to the resulting size of the destination buffer.

Description

This function performs the bzip2-specific Z1Z2 encoding.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error if one of the pointers is NULL.

ippStsSizeErr

Indicates an error if length of the source or destination buffer is less than or equal to 0.

ippStsDstSizeLessExpected
