How can I implement locks?
Hello, from what I can see pthreads are not available in amiga/vbcc? (not sure if in AmigaOS in general or just vbcc implementation). When I try to use #include <pthread.h> I get pthread.h not found.
Given this, is there any other way how I can implement a lock/release mechanism in C on Amiga OS? |

What you're looking for is semaphores, as provided by exec.library.
Check out struct SignalSemaphore, ObtainSemaphore(), ObtainSemaphoreShared(), AttemptSemaphore(), AttemptSemaphoreShared() and ReleaseSemaphore(). (I wrote some threading code many years ago - I just remembered it's still online! Maybe it'll be helpful: http://blackfiveservices.co.uk/amiga...hreads_amr.lha ) |
