.IR Note :
There is no glibc wrapper for this system call; see NOTES.
glibc provides no wrapper for
.BR spu_create (),
necessitating the use of
.BR syscall (2).

architecture.
Programs using this system call are not portable.
.SH NOTES
Glibc does not provide a wrapper for this system call; call it using
.BR syscall (2).
Note however, that
.BR spu_create ()
is meant to be used from libraries that implement a more abstract
interface to SPUs, not to be used from regular applications.
