Function io_uring_queue_mmap 

pub unsafe extern "C" fn io_uring_queue_mmap(
    fd: c_int,
    p: *mut io_uring_params,
    ring: *mut io_uring,
) -> c_int

Mmap io_uring ring after setup

DESCRIPTION

The io_uring_queue_mmap function maps the io_uring ring file descriptor fd into memory using the parameters in p. The resulting ring is stored in ring.

This function is a helper for applications that need to customize the ring setup process. Most applications should use io_uring_queue_init or io_uring_queue_init_params instead, which call io_uring_setup and this function automatically.

The fd argument should be a file descriptor returned by io_uring_setup, and p should contain the parameters returned by the setup call.

RETURN VALUE

Returns 0 on success, or a negative errno value on error.
