comedi_arm — arm a subdevice
|comedi_t * device,|
|unsigned int subdevice,|
|unsigned int source|
This function arms a subdevice. It may, for example, arm a counter to
begin counting. The
parameter specifies what source should trigger the subdevice to begin.
The possible sources are driver-dependant. This function is only
useable on subdevices that provide support for the
INSN_CONFIG_ARM configuration instruction.
Some subdevices treat this as an instruction to arm a specific channel.
For those subdevices, this function will arm channel
should be called instead of this one to specify the channel.
