Function futex_4arg [src]

Four-argument variation on the v1 futex call. Only suitable for futex_op that ignores the remaining arguments (e.g., FUTEX_OP.WAIT).

Prototype

pub fn futex_4arg(uaddr: *const anyopaque, futex_op: FUTEX_OP, val: u32, timeout: ?*const timespec) usize

Parameters

uaddr: *const anyopaquefutex_op: FUTEX_OPval: u32timeout: ?*const timespec

Source

  pub fn futex_4arg(uaddr: *const anyopaque, futex_op: FUTEX_OP, val: u32, timeout: ?*const timespec) usize {
    return syscall4(
        if (@hasField(SYS, "futex")) .futex else .futex_time64,
        @intFromPtr(uaddr),
        @as(u32, @bitCast(futex_op)),
        val,
        @intFromPtr(timeout),
    );
