NAME
     io_uring_register_probe - register probe with io_uring

SYNOPSIS
     #include <liburing.h>

     int io_uring_register_probe(struct io_uring *ring,
				 struct io_uring_probe *p,
				 unsigned nr);

DESCRIPTION
     The  io_uring_register_probe(3)  function	queries the kernel for supported
     io_uring opcodes and fills in the probe structure	p.   The  ring	argument
     specifies the io_uring instance to query, and nr specifies the maximum num-
     ber of opcodes to query.

     The  probe structure contains information about which opcodes are supported
     by the kernel. Applications can use io_uring_opcode_supported(3)  to  check
     if a specific opcode is supported after calling this function.

     Most    applications    should    use   io_uring_get_probe(3)   or	  io_ur-
     ing_get_probe_ring(3) instead, which allocate and fill in the probe  struc-
     ture automatically.


RETURN VALUE
     Returns 0 on success. On error, a negative errno value is returned.
