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