NAME         top

       io_uring_prep_mkdirat - prepare an mkdirat request

SYNOPSIS         top

       #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         top

       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         top

       None

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
       field.

NOTES         top

       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).
