open_how(2type) open_how(2type)
open_how - how to open a pathname
Linux kernel headers
#include <linux/openat2.h> struct open_how { u64 flags; /* O_* flags */ u64 mode; /* Mode for O_{CREAT,TMPFILE} */ u64 resolve; /* RESOLVE_* flags */ /* ... */ };
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).
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.
