#include <sys/lwp.h> int _lwp_suspend(lwpid_t target_lwp);
int _lwp_continue(lwpid_t target_lwp);
The _lwp_suspend() function immediately suspends the execution of the LWP specified by target_lwp. On successful return from _lwp_suspend(), target_lwp is no longer executing. Once a thread is suspended, subsequent calls to _lwp_suspend() have no affect.
The _lwp_continue() function resumes the execution of a suspended LWP. Once a suspended LWP is continued, subsequent calls to _lwp_continue() have no effect.
A suspended LWP will not be awakened by a signal. The signal stays pending until the execution of the LWP is resumed by _lwp_continue().
Upon successful completion, 0 is returned. A non-zero value indicates an error.
If the following condition occurs, _lwp_suspend() and _lwp_continue() fail and return the corresponding value:
ESRCH
The target_lwpid argument cannot be found in the current process.
