NAME
       io_uring_get_probe_ring - get probe information from an existing ring

SYNOPSIS
       #include <liburing.h>

       struct io_uring_probe *io_uring_get_probe_ring(struct io_uring *ring);

DESCRIPTION
       The io_uring_get_probe_ring(3) function returns probe information for
       the io_uring instance specified by ring.  This allows the application
       to determine which opcodes are supported by the kernel.

       The returned probe structure and must be freed by the application using
       io_uring_free_probe(3) when no longer needed.

       This function is similar to io_uring_get_probe(3), except it uses an
       existing ring instead of creating a temporary one.


RETURN VALUE
       Returns a pointer to an allocated struct io_uring_probe on success, or
       NULL on failure.
