.SH NAME
usb_ep_set_halt \- sets the endpoint halt feature.
.SH SYNOPSIS
.sp
\fB
.sp
int usb_ep_set_halt  (struct usb_ep * \fIep\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIep\fB\fR
the non-isochronous endpoint being stalled
.SH "DESCRIPTION"
.PP
Use this to stall an endpoint, perhaps as an error report.
Except for control endpoints,
the endpoint stays halted (will not stream any data) until the host
clears this feature; drivers may need to empty the endpoint's request
queue first, to make sure no inappropriate transfers happen.
.PP
Returns zero, or a negative error code.  On success, this call sets
underlying hardware state that blocks data transfers.
