pub struct Fadvise { /* private fields */ }
Expand description

Predeclare an access pattern for file data, equivalent to posix_fadvise(2).

Implementations§

impl Fadvise

source

pub fn new(fd: impl UseFixed, len: off_t, advice: i32) -> Self

source

pub const CODE: u8 = 24u8

The opcode of the operation. This can be passed to Probe::is_supported to check if this operation is supported with the current kernel.
