open_how(2type) open_how(2type)
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 com-
ponents of a pathname will be resolved (see path_resolution(7)
for background information).
VERSIONS
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.
STANDARDS
Linux.
