apue thread posix thread posix线程相关

pthread_t

pthread_equal

pthread_self

int pthread_create(pthread_t *tidp, const pthred_attr_t *attr,

void *(*start_rtn)(void *), void *arg)

thread退出:

1 start routine return

2 另外一个线程终结cancel. int pthread_cancel( pthread_t tid);

doestn't wait, merely make the request(async)

thread_cleanup handlers

pthread_cleanup_push( void (*rtn)(void *),void *arg)

pthread_cleanup_pop( int execute)

3 pthread_exit

void pthread_eixt( void *rval_ptr)

会被另外的线程

int pthread_join( pthread_t thread, void **rval_prt)

1 包含start routine返回的返回码

2 PTHREAD_CANCELED

3 

pthread_detach for a detached thread results in undefined behavior

1 Thread limits 

sysconf
