int SetOutput (object obj, void shader_output, int index, arbitraryvalue )

Return Value: 1 = success, 0 = failure

Arguments:

Sets the value of a shader's output. You tell messiah which output you wish to adjust by sepcifing an index value, you should have previously stored this value as returned by fxShaderCreateOutput. Both the obj and the shader_output 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.
