[−][src]Function linux::syscall::set_tid_address

pub unsafe fn set_tid_address(tidptr: Option<&AtomicInt>) -> c_int

Sets the address on which the kernel will perform a futex_wake operation upon thread exit.

[argument, tidptr] The address or None to disable this feature.

[return_value] Returns the callers thread id.

= Remarks

The kernel will first write 0 to this address and then perform a futex_wake.

This is unsafe because the address might no longer be valid when the thread exits.
