Returns the pointer to the filter coefficients.
Syntax
IppStatus ippsFIRLMSMRGetTapsPointer32s_16s(IppsFIRLMSMRState32s_16s* pState, Ipp32s** ppTaps);
IppStatus ippsFIRLMSMRGetTapsPointer32sc_16sc(IppsFIRLMSMRState32sc_16sc* pState, Ipp32sc** ppTaps);
Parameters
pState |
Pointer to the filter state structure. |
ppTaps |
Pointer to the variable that contains the pointer to the tap values. |
Description
The function ippsFIRLMSMRGetTapsPointer is declared in the ipps.h file. This function writes the pointer to the filter coefficients stored in the filter state structure pState to the variable pointed by pTaps.
Caution
To get the pointer to tap values directly is faster than to copy them using the the function ippsFIRLMSMRGetTaps function, but this operation may be error-prone.
Before calling the function ippsFIRLMSMRGetTapsPointer the filter state structure must be initialized by the the function ippsFIRLMSMRInitAlloc.
Return Values
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error when one of the specified pointers is NULL. |
ippStsContextMatchErr |
Indicates an error when the state identifier is incorrect. |
