27 * Win32 implementation of mutexes. Here we use critical sections as |
|
28 * our mutexes. We could have used mutexes, but mutexes are heavier |
|
29 * weight than critical sections. Mutexes and critical sections are |
|
30 * semantically identical, the only difference being that mutexes |
|
31 * can operate between processes (i.e. address spaces). |
|
32 * |
|
33 * It's worth noting that the Win32 functions supporting critical |
|
34 * sections do not provide any error information whatsoever (i.e. |
|
35 * all critical section routines return (void)). |
