pState |
Pointer to the IIRIIR filter state structure. |
pDlyLine |
Pointer to the array containing the delay line values. The number of elements in the array is order. |
This function copies the delay line values from the corresponding pState structure and stores them into the pDlyLine array.
The corresponding filter state structure must be initialized beforehand by the initialization function.
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error when the pState pointer is NULL. |
ippStsContextMatchErr |
Indicates an error when the state identifier is incorrect. |
