cgSetParameter4f(3)

NAME
cgSetParameter4f - set the value of scalar and vector parameters

SYNOPSIS
  #include <Cg/cg.h>
  void cgSetParameter4f( CGparameter param,
                         float x,
                         float y,
                         float z,
                         float w );

PARAMETERS
The parameter that will be set. The values used to set param.

RETURN VALUES
None.

DESCRIPTION
cgSetParameter4f 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 cgSetParameter4f 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
to-be-written

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
cgSetParameter4f was introduced in Cg 1.2.
