It works, in that the disk gets unmounted, but my callback isn't being called, even though the operation is successful. Any chance of spotting the mistake in this code fragment? :- Cheers, Andy 8<---- struct Nothing { bool dummy; }; static void AndygDiskArbCallback( DADiskRef disk, DADissenterRef dissenter, void * context) { printf("If I ever see this, my problems are over\n"); Nothing * n = (Nothing *)context; n->dummy = true; // I want to give a semaphore here to unlock the main thread } int main(int argc, char *argv[]) { const char * cStr = "disk0s2"; Nothing * n = new Nothing; n->dummy = false; DASessionRef diskArbSession = DASessionCreate(kCFAllocatorDefault); assert(diskArbSession); DADiskRef disk = DADiskCreateFromBSDName( kCFAllocatorDefault, diskArbSession, cStr ); assert(disk); printf("confirming %s == %s??\n", DADiskGetBSDName(disk), cStr); DADiskRef whole = DADiskCopyWholeDisk( disk ); if ( whole ) { printf("wholedisk == %s\n", DADiskGetBSDName(whole)); DADiskUnmount(whole, kDADiskUnmountOptionWhole | kDADiskUnmountOptionForce, AndygDiskArbCallback, n); CFRelease(whole); } printf("------Wait..."); sleep(1); // instead of sleep, I want to wait on a semaphore here, until the unmount is complete. // unfortunately the callback isn't being called! // I'll do this too, once I get the callback from Unmount... // DADiskEject( disk, kDADiskEjectOptionDefault, AndygDiskArbCallback, NULL ); CFRelease(disk); CFRelease(diskArbSession); printf("AT THE END OF IT ALL, n=%d\n", n->dummy); delete(n); } _______________________________________________ Do not post admin requests to the list.
