18 This function arms a specified channel of a subdevice. It may, for
19 example, arm a counter to begin counting. The source parameter
20 specifies what source should trigger the subdevice to begin. The
21 possible sources are driver-dependant. This function is only useable on
22 subdevices that provide support for the INSN_CONFIG_ARM configuration
23 instruction. Some subdevices treat this as an instruction to arm the
24 whole subdevice and ignore the specified channel. For such subdevices,
25 comedi_arm is normally called instead.
