cgGetNamedPassAnnotation(3)

NAME
cgGetNamedPassAnnotation - get a pass annotation by name

SYNOPSIS
  #include <Cg/cg.h>
  CGannotation cgGetNamedPassAnnotation( CGpass pass,
                                         const char * name );

PARAMETERS
The pass from which to retrieve the annotation. 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.
