IppStatus ippiWTFwdFree_32f_C3R (IppiWTFwdSpec_32f_C3R* pSpec);

Parameters

pSpec: Pointer to an allocated and initialized forward DWT context structure.

Description

The function ippiWTFwdFree is declared in the ippi.h file. This function frees memory previously allocated by the function ippiWTFwdFree for a forward wavelet transform context structure pSpec.

Example “Using Intel IPP Functions for Wavelet Transforms” shows how to use the function ippiWTFwdFree_32f_C1R.

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr	Indicates an error condition if pSpec pointer is `NULL`.
