Parameters

pState	Pointer to the FIR filter state structure.
pDlyLine	Pointer to the array holding the delay line values.

Description

The function ippsFIRSetDlyLine is declared in the ipps.h file. This function copies the delay line values from pDlyLine and stores them into the state structure pState. The source array pDlyLine must contain samples in the reverse order as compared to the order of samples in the source vector.

Before calling ippsFIRGetDlyLine the corresponding filter state structure must be initialized by calling the ippsFIRInitAlloc or ippsFIRMRInitAlloc.

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.
