.BI "int comedi_get_cmd_generic_timed(comedi_t\ *\ " "device" ", unsigned\ int\ " "subdevice" ", comedi_cmd\ *\ " "command" ", unsigned\ int\ " "chanlist_len" ", unsigned\ int\ " "scan_period_ns" ");"
.SH "DESCRIPTION"
.PP
The command capabilities of the subdevice indicated by the parameters
\fIdevice\fR
and
\fIsubdevice\fR
are probed, and the results placed in the command structure pointed to by the parameter
\fIcommand\fR\&. The command structure pointed to by
\fIcommand\fR
is modified to be a valid command that can be used as a parameter to
\fBcomedi_command\fR
(after the command has additionally been assigned a valid
\fIchanlist\fR
array)\&. The command measures scans consisting of
\fIchanlist_len\fR
channels at a scan rate that corresponds to a period of
\fIscan_period_ns\fR
nanoseconds\&. The rate is adjusted to a rate that the device can handle\&.
.SH "RETURN VALUE"
.PP
On success,
0
is returned\&. On failure,
\-1
is returned\&.
