NAME         top

       io_uring_prep_madvise - prepare a madvise request

SYNOPSIS         top

       #include <sys/mman.h>
       #include <liburing.h>

       void io_uring_prep_madvise(struct io_uring_sqe *sqe,
                                  void *addr,
                                  off_t len,
                                  int advice);

DESCRIPTION         top

       The io_uring_prep_madvise(3) function prepares an madvise
       request. The submission queue entry sqe is setup to start an
       madvise operation at the virtual address of addr and of len
       length in bytes, giving it the advise located in advice.

       This function prepares an async madvise(2) request. See that man
       page for details.

RETURN VALUE         top


ERRORS         top

       The CQE res field will contain the result of the operation. See
       the related man page for details on possible values. Note that
       where synchronous system calls will return -1 on failure and set
       errno to the actual error value, io_uring never uses errno.
       Instead it returns the negated errno directly in the CQE res
