create a new thread
*), void *arg);
pthread_create() function is used to
create a new thread, with attributes specified by
attr, within a process. If attr
is NULL, the default attributes are used. If the attributes specified by
attr are modified later, the thread's attributes are
not affected. Upon successful completion
pthread_create() will store the ID of the created
thread in the location specified by thread.
The thread is created executing
start_routine with arg as its
sole argument. If the start_routine returns, the
effect is as if there was an implicit call to
pthread_exit() using the return value of
start_routine as the exit status. Note that the thread
main() was originally invoked differs from
this. When it returns from
main(), the effect is as
if there was an implicit call to
exit() using the
return value of
main() as the exit status.
The signal state of the new thread is initialized as:
If successful, the
function will return zero. Otherwise an error number will be returned to
indicate the error.
pthread_create() will fail if:
__tfork(3), pthread_attr_init(3), pthread_attr_setdetachstate(3), pthread_attr_setguardsize(3), pthread_attr_setstack(3), pthread_attr_setstackaddr(3), pthread_attr_setstacksize(3), pthread_cleanup_pop(3), pthread_cleanup_push(3), pthread_exit(3), pthread_join(3)
pthread_create() conforms to
ISO/IEC 9945-1:1996 (“POSIX.1”).
