	status.i4.v = scope_set_edge_trigger_params_c(connect_info.g.v,

						      [,slope.i4.v])

	This routine sets edge trigger parameters for a scope.

	connect_info	scope connection structure created by a
			prior call to scope_connect
	trigger		trigger to set
			(SCOPE_TRIGGER_A -> trigger A (normal choice),
			 SCOPE_TRIGGER_B -> trigger B)
	[source]	desired trigger source
			(CLIB_DEFAULT_ARG -> use previous value (default),
			 SCOPE_TRIGGER_SOURCE_EXTERNAL -> external trigger,
			 SCOPE_TRIGGER_SOURCE_LINE -> line voltage,
			 SCOPE_TRIGGER_SOURCE_CH1 -> channel 1,
			 SCOPE_TRIGGER_SOURCE_CH2 -> channel 2,
			 SCOPE_TRIGGER_SOURCE_CH3 -> channel 3,
			 SCOPE_TRIGGER_SOURCE_CH4 -> channel 4)
	[coupling]	desired trigger coupling
			(CLIB_DEFAULT_ARG -> use previous value (default),
			 SCOPE_TRIGGER_COUPLING_DC -> DC,
			 SCOPE_TRIGGER_COUPLING_AC -> AC,
			 SCOPE_TRIGGER_COUPLING_HF_REJECT -> high frequency
							     reject,
			 SCOPE_TRIGGER_COUPLING_LF_REJECT -> low frequency
							     reject,
			 SCOPE_TRIGGER_COUPLING_NOISE_REJECT -> noise reject)
	[slope]		desired trigger slope
			(CLIB_DEFAULT_ARG -> use previous value (default),
			 SCOPE_TRIGGER_SLOPE_RISING -> rising edge,
			 SCOPE_TRIGGER_SLOPE_FALLING -> falling edge)

	This function returns ACNET status values as follows:

	OK			success
	CLIB_NOTYET		scope model is not supported
	CLIB_INVARG		invalid connection information passed
	CLIB_GENERIC_ERROR	error accessing scope information
	otherwise		other ACNET error

	This function requires the following include files:

	ul_scopes_h:scopelib_h, acnet_errors_h
