Name

cgSetParameter4iv - sets the value of scalar and vector parameters

Synopsis

#include <Cg/cg.h>

void cgSetParameter4iv( CGparameter param,
                        const int * v );

Parameters

param

The parameter that will be set.

v

Array of values to use to set param.

Return Values

None.

Description

cgSetParameter4iv 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 cgSetParameter4iv 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

cgSetParameter4iv was introduced in Cg 1.4.
