FUNCTION RHEL ORACLE SOLARIS 11
int pthread_cancel(pthread_t
thread);
On Linux, cancellation is
implemented using signals. Under
the NPTL threading
implementation, the first real-time
signal (that is, signal 32) is used for
this purpose. On LinuxThreads, the
second real-time signal is used if
real-time signals are available;
otherwise, SIGUSR2 is used.
A thread acting on a cancellation request runs
with all signals blocked. All thread termination
functions, including cancellation cleanup
handlers and thread-specific data destructor
functions, are called with all signals blocked. The
cancellation processing in target_thread
runs asynchronously with respect to the calling
thread returning from pthread_cancel().
