USB_ALLOC_STREAMS(9)					       Host Controller APIs					      USB_ALLOC_STREAMS(9)

NAME
       usb_alloc_streams - allocate bulk endpoint stream IDs.

SYNOPSIS
       int usb_alloc_streams(struct usb_interface * interface, struct usb_host_endpoint ** eps, unsigned int num_eps, unsigned int num_streams,
			     gfp_t mem_flags);

ARGUMENTS
       interface
	   alternate setting that includes all endpoints.

       eps
	   array of endpoints that need streams.

       num_eps
	   number of endpoints in the array.

       num_streams
	   number of streams to allocate.

       mem_flags
	   flags hcd should use to allocate memory.

DESCRIPTION
       Sets up a group of bulk endpoints to have num_streams stream IDs available. Drivers may queue multiple transfers to different stream IDs,
       which may complete in a different order than they were queued.

RETURN
       On success, the number of allocated streams. On failure, a negative error code.
