cgGetNamedEffect(3)

NAME
cgGetNamedEffect - get an effect from a context by name

SYNOPSIS
  #include <Cg/cg.h>
  CGeffect cgGetNamedEffect( CGcontext context,
                             const char * name );

PARAMETERS
The context from which to retrieve the effect. The name of the effect to retrieve.

RETURN VALUES
Returns the named effect if found.

Returns NULL if context has no effect corresponding to name or if an error occurs.

DESCRIPTION
The effects in a context can be retrieved directly by name using cgGetNamedEffect. The effect names can be discovered by iterating through the context's effects (see the cgGetFirstEffect manpage and the cgGetNextEffect manpage) and calling the cgGetEffectName manpage for each.

EXAMPLES
  /* get "simpleEffect" from context */
  CGeffect effect = cgGetNamedEffect( context, "simpleEffect" );

ERRORS
CG_INVALID_CONTEXT_HANDLE_ERROR is generated if context is not a valid context.

HISTORY
cgGetNamedEffect was introduced in Cg 1.5.
