int SetInput (object obj, void shader_input, int index, arbitraryvalue )

Return Value: 1 = success, 0 = failure

Arguments:

Sets the value of a shader's input. You tell messiah which input you wish to adjust by sepcifing an index value, you should have previously stored this value as returned by fxShaderCreateInput.Both the obj and the shader_input values are passed to your shader function by messiah, if messiah doesn't pass these values to a particular function it should be assumed that it is not safe to call this function from there.
