NAME

cgGetNumParentTypes - gets the number of parent types of a given type

SYNOPSIS


  #include <Cg/cg.h>







  int cgGetNumParentTypes( CGtype type );

PARAMETERS


type
The child type.

RETURN VALUES

Returns the number of parent types.

Returns 0 if there are no parents.

DESCRIPTION

cgGetNumParentTypes returns the number of parents from which type inherits.

A parent type is one from which the given type inherits, or an interface type that the given type implements.

Note that the current Cg language specification implies that a type may only have a single parent type --- an interface implemented by the given type.

EXAMPLES

Given the type definitions: 

    interface myiface {

        float4 eval(void);

    };







    struct mystruct : myiface {

        float4 value;

        float4 eval(void ) { return value; }

    };
mystruct has a single parent type, myiface.

ERRORS

None.

HISTORY

cgGetNumParentTypes was introduced in Cg 1.2.
