NAME
cgGLSetParameter4f - set the values of scalar and vector parameters
SYNOPSIS
#include <Cg/cgGL.h> void cgGLSetParameter4f( CGparameter param, float x, float y, float z, float w );PARAMETERS
- param
The parameter that will be set.
- x, y, z, w
The values to which param will be set.
RETURN VALUES
None.
DESCRIPTION
cgGLSetParameter4f sets the value of a given scalar or vector parameter.
If more values are passed in than the parameter requires, the extra values will be ignored. If fewer values are passed in than the parameter requires, w will be smeared.
cgGLSetParameter4f may be called with uniform or varying parameters. When called with a varying parameter, the appropriate immediate mode OpenGL entry point will be called. However, the cgGLGetParameter functions only work with uniform parameters.

ERRORS
CG_INVALID_PROFILE_ERROR is generated if param's profile is not a supported OpenGL profile.
CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter handle.
CG_INVALID_PARAMETER_ERROR is generated if the parameter fails to set for any other reason.
HISTORY
cgGLSetParameter4f was introduced in Cg 1.1.
