Parameters
order
Order of the IIR filter.
pBufferSize
Pointer to the computed buffer size value.
Description
This function computes the size of the external buffer for an arbitrary IIR filter state, and stores the result in
pBufferSize
.
To compute a size of the buffer, the filter order parameter
order
must be specified.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error when
pBufferSize
pointer is
NULL
.
ippStsIIROrderErr
Indicates an error when
order
is less than or equal to 0.
