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. Before using this function, calculate the size of the structure calling the
DecodeZfpGetStateSize
function.
Use
ippsDecodeZfpInitLong
to process large 3D floating point arrays.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error if any of the pointers is
NULL
.
ippStsSizeErr
Indicates an error if the parameter
srcLen
is less than or equal to zero
(applies only to
ippsDecodeZfpInit
)
.
