NAME         top

       io_uring_get_probe_ring - get probe information from an existing
       ring

SYNOPSIS         top

       #include <liburing.h>

       struct io_uring_probe *io_uring_get_probe_ring(struct io_uring *ring);

DESCRIPTION         top

       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         top

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

       io_uring_opcode_supported(3), io_uring_register_probe(3)
