IIRIIRGetStateSize

Computes the length of the external buffer for the IIRIIR filter state structure.

Syntax

IppStatus ippsIIRIIRGetStateSize_32f(int order, int* pBufferSize);

IppStatus ippsIIRIIRGetStateSize64f_32f(int order, int* pBufferSize);

IppStatus ippsIIRIIRGetStateSize_64f(int order, int* pBufferSize);

Domain Dependencies

Headers: ippcore.h, ippvm.h

Libraries: ippcore.lib, ippvm.lib

Parameters

order

 Order of the IIRIIR filter.

pBufferSize

 Pointer to the computed buffer size value.

Description

This function computes the size of the external buffer for the IIRIIR filter state structure, and stores the result in pBufferSize.

Use this function before using IIRIIRInit.

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 zero.
