Suspends execution of the pthread specified by thread.
Threads Library (libpthreads.a)
#include <pthread.h> int pthread_suspend_np(pthread_t thread); int pthread_continue_np(pthread_t thread);
The pthread_suspend_np routine immediately suspends the execution of the pthread specified by thread. On successful return from pthread_suspend_np, the suspended pthread is no longer executing. If pthread_suspend_np is called for a pthread that is already suspended, the pthread is unchanged and pthread_suspend_np returns successful.
The pthread_continue_np routine resumes the execution of a suspended pthread. If pthread_continue_np is called for a pthread that is not suspended, the pthread is unchanged and pthread_continue_np returns successful.
A suspended pthread will not be awakened by a signal. The signal stays pending until the execution of pthread is resumed by pthread_continue_np.
thread | Specifies the target thread. |
Zero is returned when successful. A non-zero value indicates an error.
If any of the following conditions occur, pthread_suspend_np and pthread_continue_np fail and return the corresponding value:
ESRCH | The thread attribute cannot be found in the current process. |
