NAME

6       comedi_arm - arm a subdevice

SYNOPSIS

9       #include <comedilib.h>
10
11       int comedi_arm(comedi_t * device, unsigned int subdevice,
12                      unsigned int source);

STATUS

DESCRIPTION

18       This function arms a subdevice. It may, for example, arm a counter to
19       begin counting. The source parameter specifies what source should
20       trigger the subdevice to begin. The possible sources are
21       driver-dependant. This function is only useable on subdevices that
22       provide support for the INSN_CONFIG_ARM configuration instruction. Some
23       subdevices treat this as an instruction to arm a specific channel. For
24       those subdevices, this function will arm channel 0 and
25       comedi_arm_channel should be called instead of this one to specify the
26       channel.

RETURN VALUE

29       0 on success, -1 on error.
