pthread_create - create a new thread
int pthread_create(pthread_t * thread, pthread_attr_t * attr, void *
(*start_routine)(void *), void * arg);
!pthread_create! creates a new thread of control that executes
concurrently with the calling thread. The new thread applies the
function |start_routine| passing it |arg| as first argument. The new
thread terminates either explicitly, by calling !pthread_exit!(3), or
implicitly, by returning from the |start_routine| function. The latter
case is equivalent to calling !pthread_exit!(3) with the result
returned by |start_routine| as exit code.
The |attr| argument specifies thread attributes to be applied to the
new thread. See !pthread_attr_init!(3) for a complete list of thread
attributes. The |attr| argument can also be !NULL!, in which case
default attributes are used: the created thread is joinable (not
detached) and has default (non real-time) scheduling policy.
On success, the identifier of the newly created thread is stored in the
location pointed by the |thread| argument, and a 0 is returned. On
error, a non-zero error code is returned.
not enough system resources to create a process for the new
more than !PTHREAD_THREADS_MAX! threads are already active.
