ARGUMENTS

display: Specifies the connection to the X server.
dst: Destination sample buffer.
dst_index: Index of first sample of destination sample buffer.
src: Source sample buffer.
src_index: Index of first sample of source sample buffer.
src1: Source sample buffer.
src1_index: Index of first sample of source sample buffer.
src2: Source sample buffer.
src2_index: Index of first sample of source sample buffer.
count: Number of samples to compute.
constant: Constant value for arithmetic operation.
kern: Convolution kernel.
denominator: Denominator to determine scaling between src, dst and kern.
shift: Numerator shift to determine offset between src and dst.
scalesrc: Multiplier to scale src with respect to kern.
scaledst: Multiplier to scale dst with respect to kern.

DESCRIPTION

The functions correspond to the XaudioMultiplyConstant(3) , XaudioMultiplyConstantAccumulate(3) , XaudioMultiply(3) , XaudioMultiplyAccumulate(3) , XaudioConvolute(3) and XaudioConvoluteAccumulate(3) functions respectively with the only difference that the operations are not executed immediately but scheduled for a later point in time.
