Parameters
pState
Pointer to the IIR filter state structure.
pDlyLine
Pointer to the array holding the delay line values. The number of elements in the array is
order
for arbitrary filters and 2*
numBq
for BQ filters. If the pointer is
NULL
, then the delay line values in the state structure are initialized to zero.
Description
This function copies the delay line values from
pDlyLine
and stores them into the state structure
pState
. If the pointer is
NULL
, then the delay line values in the state structure are initialized to zero.
The filter state must be initialized beforehand by one of the initialization functions.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error when the
pState
pointer is
NULL
.
ippStsContextMatchErr
Indicates an error when the state identifier is incorrect.
