NAME         top

       open_how - how to open a pathname

LIBRARY         top

       Linux kernel headers

SYNOPSIS         top

       #include <linux/openat2.h>

       struct open_how {
           u64  flags;    /* O_* flags */
           u64  mode;     /* Mode for O_{CREAT,TMPFILE} */
           u64  resolve;  /* RESOLVE_* flags */
           /* ... */
       };

DESCRIPTION         top

       Specifies how a pathname should be opened.

       The fields are as follows:

       flags  This field specifies the file creation and file status
              flags to use when opening the file.

       mode   This field specifies the mode for the new file.

       resolve
              This is a bit mask of flags that modify the way in which
              all components of a pathname will be resolved (see
              path_resolution(7) for background information).

VERSIONS         top

       Extra fields may be appended to the structure, with a zero value
       in a new field resulting in the kernel behaving as though that
       extension field was not present.  Therefore, a user must zero-
       fill this structure on initialization.
