NAME
cgSetParameter4i - set the value of scalar and vector parameters
SYNOPSIS
#include <Cg/cg.h> void cgSetParameter4i( CGparameter param, int x, int y, int z, int w );PARAMETERS
- param
The parameter that will be set.
- x, y, z, w
The values used to set param.
RETURN VALUES
None.
DESCRIPTION
cgSetParameter4i sets the value of a given scalar or vector parameter.
If more values are passed in than param requires, the extra values will be ignored.
Once cgSetParameter4i has been used to set a parameter, the values may be retrieved from the parameter using the CG_CURRENT enumerant with cgGetParameterValues.
If an API-dependant layer of the Cg runtime (e.g. cgGL) is used, these entry points may end up making API (e.g. OpenGL) calls.
EXAMPLES

ERRORS
CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.
CG_INVALID_PARAMETER_ERROR is generated if param is a varying input to a fragment program.
HISTORY
cgSetParameter4i was introduced in Cg 1.4.
