> # NAME

> cgGetNextLeafParameter - get the next leaf parameter in a program or effect

> # SYNOPSIS

>       #include <Cg/cg.h>

>       CGparameter cgGetNextLeafParameter( CGparameter param );

> # PARAMETERS

> param

>   The current leaf parameter.

> # RETURN VALUES

> Returns the next leaf CGparameter object.

> Returns NULL if param is invalid or if the program or effect from which the iteration started does not have any more leaf parameters.

> # DESCRIPTION

> cgGetNextLeafParameter returns the next leaf parameter (not struct or array parameters) following a given leaf parameter.

> In a similar manner, the leaf parameters in an effect can be iterated over starting with a call to cgGetFirstLeafEffectParameter.

> # EXAMPLES

>       CGparameter leaf = cgGetFirstLeafParameter( program );
>       while(leaf)
>        {
>          /* Do stuff with leaf */
>          leaf = cgGetNextLeafParameter( leaf );
>        }

> # ERRORS

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

> # HISTORY

> cgGetNextLeafParameter was introduced in Cg 1.1.
