cgGetNextEffect(3)

NAME
cgGetNextEffect - iterate through effects in a context

SYNOPSIS
  #include <Cg/cg.h>
  CGeffect cgGetNextEffect( CGeffect effect );

PARAMETERS
The current effect.

RETURN VALUES
Returns the next effect in the context's internal sequence of effects.

Returns NULL when effect is the last effect in the context.

DESCRIPTION
The effects within a context can be iterated over with cgGetNextEffect.

Note that no specific order of traversal is defined by this mechanism. The only guarantee is that each effect will be visited exactly once. No guarantees can be made if effects are created or deleted during iteration.

EXAMPLES
  CGeffect effect = cgGetFirstEffect( context );
  while( effect )
  {
    /* do something with effect */
    effect = cgGetNextEffect( effect );
  }

ERRORS
CG_INVALID_EFFECT_HANDLE_ERROR is generated if effect is not a valid effect.

HISTORY
cgGetNextEffect was introduced in Cg 1.4.
