NAME

       comedi_internal_trigger - generate soft trigger

SYNOPSIS

       #include <comedilib.h>

       int comedi_internal_trigger(comedi_t * device, unsigned int subdevice,
                                   unsigned int trig_num);

DESCRIPTION

       This function sends an INSN_INTTRIG instruction to a subdevice, which causes an internal
       triggering event. This event can, for example, trigger a subdevice to start an
       asynchronous command.

       The trig_num parameter is reserved for future use, and should be set to 0. It is likely it
       will be used in the future to support multiple independent internal triggers. For example,
       an asynchronous command might be specified for a subdevice with a start_src of TRIG_INT,
       and a start_arg of 5. Then the start event would only be triggered if
       comedi_internal_trigger were called on the subdevice with a trig_num equal to the same
       value of 5.

RETURN VALUE

       0 on success, -1 on error.
