Function futex2_wait [src]

Wait on a futex. Identical to the traditional FUTEX.FUTEX_WAIT_BITSET op, except it is part of the futex2 familiy of calls.

Prototype

 pub fn futex2_wait( uaddr: *const anyopaque, val: usize, mask: usize, flags: u32, timeout: ?*const timespec, clockid: clockid_t, ) usize

Parameters

uaddr: *const anyopaqueAddress of the futex to wait on.

val: usizeValue of uaddr.

mask: usizeBitmask.

flags: u32FUTEX2 flags.

timeout: ?*const timespecOptional absolute timeout.

clockid: clockid_tClock to be used for the timeout, realtime or monotonic.
