NAME

       io_uring_prep_mkdirat - prepare an mkdirat request

SYNOPSIS

       #include <fcntl.h>
       #include <sys/stat.h>
       #include <liburing.h>

       void io_uring_prep_mkdirat(struct io_uring_sqe *sqe,
                                  int dirfd,
                                  const char *path,
                                  mode_t mode);

       void io_uring_prep_mkdir(struct io_uring_sqe *sqe,
                                const char *path,
                                mode_t mode);

DESCRIPTION

       The  io_uring_prep_mkdirat(3)  function  prepares  a mkdirat request. The submission queue
       entry sqe is setup to use the directory file descriptor pointed to by  dirfd  to  start  a
       mkdirat operation on the path identified by path with the mode given in mode.

       The  io_uring_prep_mkdir(3)  function prepares a mkdir request. The submission queue entry
       sqe is setup to use the current working directory to start a mkdir operation on  the  path
       identified by path with the mode given in mode.

       These  functions  prepare an async mkdir(2) or mkdirat(2) request. See those man pages for
       details.

RETURN VALUE

       None

ERRORS

       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 field.

NOTES

       As with any request that passes in data in a struct, that data must remain valid until the
       request has been successfully submitted. It need not remain valid until completion. Once a
       request  has  been  submitted,  the in-kernel state is stable. Very early kernels (5.4 and
       earlier) required state to be stable until the completion occurred. Applications can  test
       for  this  behavior  by  inspecting  the  IORING_FEAT_SUBMIT_STABLE  flag passed back from
       io_uring_queue_init_params(3).
