C/C ++: multi-thread programming BASICS (2)

Http://blog.csdn.net/lzx_bupt/article/details/6910597

On the basis of thinking, what if the function called by the thread is in a class? The answer is to write the function as a static member function. The following mode conforms to the C ++ writing mode:

[CPP] View plaincopy

2. # Include <iostream>
4. # Include <pthread. h>
8. Using NamespaceSTD;
12. # Define num_threads 5
16. ClassHello
18. {
20. Public:
24. Static Void* Say_hello (Void* ARGs)// There is no difference except for the static keyword;
26. {
28. Cout <"Hello ..."<Endl;
30. }
32. };
36. IntMain ()
38. {
40. Pthread_t tids [num_threads];
42. For(IntI = 0; I <num_threads; ++ I)
44. {
46. IntRet = pthread_create (& tids [I], null, hello: say_hello, null );
48. If(Ret! = 0)
50. {
52. Cout <"Pthread_create error: error_code ="<RET <Endl;
54. }
56. }
60. Pthread_exit (null );
62. }
