.SH "ARGUMENTS"
.PP
\fIinterface\fR

.PP
\fIeps\fR
.RS 4
array of endpoints that need streams\&.

.RS 4
number of endpoints in the array\&.

.SH "DESCRIPTION"
.PP
Sets up a group of bulk endpoints to have
\fInum_streams\fR
stream IDs available\&. Drivers may queue multiple transfers to different stream IDs, which may complete in a different order than they were queued\&.
.SH "RETURN"
.PP
On success, the number of allocated streams\&. On failure, a negative error code\&.
