11 int comedi_get_cmd_generic_timed(comedi_t * device,
12 unsigned int subdevice,
13 comedi_cmd * command,
14 unsigned int chanlist_len,
15 unsigned int scan_period_ns);
16
18 The command capabilities of the subdevice indicated by the parameters
19 device and subdevice are probed, and the results placed in the command
20 structure pointed to by the parameter command. The command structure
21 pointed to by command is modified to be a valid command that can be
22 used as a parameter to comedi_command (after the command has
23 additionally been assigned a valid chanlist array). The command
24 measures scans consisting of chanlist_len channels at a scan rate that
25 corresponds to a period of scan_period_ns nanoseconds. The rate is
26 adjusted to a rate that the device can handle.

29 On success, 0 is returned. On failure, -1 is returned.
