.SH DESCRIPTION

\fIe1432_get_samples_to_pre_arm\fR returns the number of samples in the data
FIFO from the first sample to the pre_arm condition.  This information can
be used to find the tachometer times of the first sample of a block of data.

\fIhw\fR must be the result of a successful call to
\fIe1432_assign_channel_numbers\fR, and specifies the group of
hardware to talk to.

\fIID\fR is either the ID of a group of channels that was obtained with a
call to \fIe1432_create_channel_group\fR, or the ID of a single
channel.

\fIsamples\fR is the number of samples from the first sample to the pre_arm
condition.

.SH "RESET VALUE"

.SH "RETURN VALUE"
Return 0 if successful, a (negative) error number otherwise.
