suspend LWP execution
int _lwp_suspend(lwpid_t target_LWP);
LWP ID of the lightweight process (LWP) to be suspended
_lwp_suspend causes suspension of
the execution of target_LWP.
This suspended state is orthogonal
to stopped states resulting from
job control or /proc manipulations.
The function _lwp_suspend does not return
until target_LWP has actually been suspended.
No execution of a suspended LWP is possible.
if a signal is posted to a suspended LWP,
the handler cannot execute,
so the signal remains pending.
(The _lwp_kill call in the posting LWP
returns normally even if the target LWP is suspended.)
The suspended state and the /proc/debugger stop states
_lwp_suspend returns zero for success
and an error number for failure,
as described below.
If any of the following conditions is detected,
returns the corresponding value:
No LWP can be found in the current process
with identity target_LWP.
target_LWP is the calling LWP,
and the process has only one LWP.
Lightweight processes (LWPs) are internal interfaces
and are subject to change.
Their use should be avoided.
