WTInvFree

Frees memory allocated for an inverse wavelet transform context structure.

Syntax

IppStatus ippiWTInvFree_32f_C1R (IppiWTInvSpec_32f_C1R* pSpec);

IppStatus ippiWTInvFree_32f_C3R (IppiWTInvSpec_32f_C3R* pSpec);

Parameters

pSpec
Pointer to an allocated and initialized inverse DWT context structure.

Description

The function ippiWTInvFree is declared in the ippi.h file. This function frees memory that is previously allocated by the function ippiWTInvInitAlloc for the inverse wavelet transform context structure pSpec.

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

ippStsContextMatchErr

Indicates an error condition if a pointer to an invalid context structure is passed.
