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.
