> # NAME

> cgGetNamedPassAnnotation - get a pass annotation by name

> # SYNOPSIS

>       #include <Cg/cg.h>

>       CGannotation cgGetNamedPassAnnotation( CGpass pass,
>                                              const char * name );

> # PARAMETERS

> pass

>   The pass from which to retrieve the annotation.

> name

>   The name of the annotation to retrieve.

> # RETURN VALUES

> Returns the named annotation.

> Returns NULL if the pass has no annotation corresponding to name.

> # DESCRIPTION

> The annotations associated with a pass can be retrieved directly by name using cgGetNamedPassAnnotation. The names of a pass's annotations can be discovered by iterating through the annotations (see cgGetFirstPassAnnotation and cgGetNextAnnotation), calling cgGetAnnotationName for each one in turn.

> # EXAMPLES

>       /* fetch annotation "Apple" from CGpass pass */
>       CGannotation ann = cgGetNamedPassAnnotation( pass, "Apple" );

> # ERRORS

> CG_INVALID_PASS_HANDLE_ERROR is generated if pass is not a valid pass.

> # HISTORY

> cgGetNamedPassAnnotation was introduced in Cg 1.4.

> # SEE ALSO
