NAME
    cgGetParameterClass - get a parameter's class

SYNOPSIS
      #include <Cg/cg.h>

      CGparameterclass cgGetParameterClass( CGparameter param );

PARAMETERS
    param   The parameter.

RETURN VALUES
    Returns the parameter class enumerant of param.

    Returns CG_PARAMETERCLASS_UNKNOWN if an error occurs.

DESCRIPTION
    cgGetParameterClass allows the application to retrieve the class of a
    parameter.

    The returned CGparameterclass value enumerates the high-level parameter
    classes:

    CG_PARAMETERCLASS_SCALAR
                The parameter is of a scalar type, such as CG_INT, or
                CG_FLOAT.

    CG_PARAMETERCLASS_VECTOR
                The parameter is of a vector type, such as CG_INT1, or
                CG_FLOAT4.

    CG_PARAMETERCLASS_MATRIX
                The parameter is of a matrix type, such as CG_INT1x1, or
                CG_FLOAT4x4.

    CG_PARAMETERCLASS_STRUCT
                The parameter is a struct or interface.

    CG_PARAMETERCLASS_ARRAY
                The parameter is an array.

    CG_PARAMETERCLASS_SAMPLER
                The parameter is a sampler.

    CG_PARAMETERCLASS_OBJECT
                The parameter is a texture, string, or program.

EXAMPLES
    *to-be-written*

ERRORS
    CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid
    parameter.

HISTORY
    cgGetParameterClass was introduced in Cg 1.4.
