Prototype

pub fn futex2_requeue( waiters: [*]futex_waitv, flags: u32, nr_wake: i32, nr_requeue: i32, ) usize

Parameters

waiters: [*]futex_waitvArray describing the source and destination futex.

flags: u32Unused.

nr_wake: i32Number of futexes to wake.

nr_requeue: i32Number of futexes to requeue.

Source

  pub fn futex2_requeue(
    /// Array describing the source and destination futex.
    waiters: [*]futex_waitv,
    /// Unused.
    flags: u32,
    /// Number of futexes to wake.
    nr_wake: i32,
    /// Number of futexes to requeue.
    nr_requeue: i32,
) usize {
    return syscall4(
        .futex_requeue,
        @intFromPtr(waiters),
        flags,
        @bitCast(@as(isize, nr_wake)),
        @bitCast(@as(isize, nr_requeue)),
    );
