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.
