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 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.
