DAQmxCreateCIGPSTimestampChan

int32 DAQmxCreateCIGPSTimestampChan (TaskHandle taskHandle, const char counter[], const char nameToAssignToChannel[], int32 units, int32 gpsSyncMethod, const char custScaleName[]);

Purpose

Creates a channel that uses a special-purpose counter to take a timestamp and synchronizes that counter to a GPS receiver.

Parameters

Input
Name	Type	Description
taskHandle	TaskHandle	The task to which to add the channels that this function creates.
counter	const char []	The name of the counter to use to create virtual channels.
nameToAssignToChannel	const char []	The name(s) to assign to the created virtual channel(s). If you do not specify a name, NI-DAQmx uses the physical channel name as the virtual channel name. If you specify your own names for nameToAssignToChannel, you must use the names when you refer to these channels in other NI-DAQmx functions. If you create multiple virtual channels with one call to this function, you can specify a list of names separated by commas. If you provide fewer names than the number of virtual channels you create, NI-DAQmx automatically assigns names to the virtual channels.
units	int32	The units to use to return the timestamp. Value Description DAQmx_Val_Seconds Seconds DAQmx_Val_FromCustomScale From custom scale
gpsSyncMethod	int32	The method to use to synchronize the counter to a GPS receiver. Value Description DAQmx_Val_IRIGB IRIG-B DAQmx_Val_PPS PPS DAQmx_Val_None None
customScaleName	const char []	The name of a custom scale to apply to the channel. To use this parameter, you must set units to DAQmx_Val_FromCustomScale. If you do not set units to DAQmx_Val_FromCustomScale, you must set customScaleName to NULL.

Return Value

Name	Type	Description
status	int32	The error code returned by the function in the event of an error or warning. A value of 0 indicates success. A positive value indicates a warning. A negative value indicates an error.
