SYNOPSIS

9       #include <comedilib.h>
10
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

DESCRIPTION

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.
27

RETURN VALUE

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