Struct openat2::OpenHow

#[non_exhaustive]
#[repr(C)]
pub struct OpenHow {
    pub flags: u64,
    pub mode: u64,
    pub resolve: ResolveFlags,
}

A structure that specifies how a path should be opened with openat2().

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct {{ .. }} syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

flags: u64

The file creation and file status flags to use when opening the file.

mode: u64

The mode to create the file with.

If O_CREAT or O_TMPFILE is in Self::flags, this must be 0.

resolve: ResolveFlags

Flags that modify path resolution. See ResolveFlags.

Implementations

impl OpenHow

pub fn new(flags: i32, mode: u32) -> Self

Create a new OpenHow structure with the specified flags and mode.

Since this structure is non-exhaustive, this is the only way to create an OpenHow structure. Other fields can then be modified on the returned structure.
