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).

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.
