Function futex [src]

The futex v1 syscall, see also the newer the futex2_{wait,wakeup,requeue,waitv} syscalls. The futex_op parameter is a sub-command and flags. The sub-command defines which of the subsequent paramters are relevant.

Prototype

 pub fn futex(uaddr: *const anyopaque, futex_op: FUTEX_OP, val: u32, val2timeout: futex_param4, uaddr2: ?*const anyopaque, val3: u32) usize

Parameters
