Cg Core Runtime API                        cgGetParameterClass(3)



NAME
     cgGetParameterClass - get a parameter's class

SYNOPSIS
       #include 

       CGparameterclass cgGetParameterClass( CGparameter param );


PARAMETERS
     param   The parameter.

RETURN VALUES
     Returns the parameter class enumerant of param.

     Returns CGPARAMETERCLASUNKNOWN 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:

     CGPARAMETERCLASCALAR
                 The parameter is of a scalar type, such as
                 CGINT, or CGFLOAT.

     CGPARAMETERCLASVECTOR
                 The parameter is of a vector type, such as
                 CGINT1, or CGFLOAT4.

     CGPARAMETERCLASMATRIX
                 The parameter is of a matrix type, such as
                 CGINT1x1, or CGFLOAT4x4.

     CGPARAMETERCLASTRUCT
                 The parameter is a struct or interface.

     CGPARAMETERCLASARAY
                 The parameter is an array.

     CGPARAMETERCLASAMPLER
                 The parameter is a sampler.

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