> ## Return Values

> Returns the next pass in the technique's internal sequence of passes.

> Returns NULL when pass is the last pass in the technique.

> ## Description

> The passes within a technique can be iterated over using cgGetNextPass.

> Passes are returned in the order defined in the technique.

> ## Examples

>     CGpass pass = cgGetFirstPass( technique );
>     while( pass )
>     {
>       /* do something with pass */
