DCTInvFree

Closes the inverse discrete cosine transform structure.

Syntax

IppStatus ippsDCTInvFree_16s(IppsDCTInvSpec_16s* pDCTSpec);

IppStatus ippsDCTInvFree_32f(IppsDCTInvSpec_32f* pDCTSpec);

IppStatus ippsDCTInvFree_64f(IppsDCTInvSpec_64f* pDCTSpec);

Parameters

pDCTSpec

Pointer to the inverse DCT specification structure.

Description

The function ippsDCTInvFree is declared in the ipps.h file. This function closes the inverse DCT specification structure pDCTSpec initialized by the function ippsDCTInvInitAlloc. Call the function ippsDCTInvFree after the transform is completed.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when the pDCTSpec pointer is NULL.
ippStsContextMatchErr	Indicates an error when the specification identifier pDCTSpec is incorrect.
