io_uring_get_probe_ring(3)	 liburing Manual      io_uring_get_probe_ring(3)

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 deter-
     mine 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 exist-
     ing 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.
