ssize_t usb_endpointReadTimeout | ( | int | ep, |
void * | buffer, | ||
ssize_t | size, | ||
ticks_t | timeout | ||
) |
Read up to size bytes from the USB endpoint identified by the address ep and store them in buffer.
The timeout is an upper bound on the amount of time (in ticks) elapsed before returns. If timeout is zero, the the function returns immediatly and it basically works in non-blocking fashion. A negative value for timeout means that the function can block indefinitely.
