| // Use the MACH_LOG family of macros along with a mach_error_t (kern_return_t) |
| // containing a Mach error. The error value will be decoded so that logged |
| // messages explain the error. |
| // |
| // Use the BOOTSTRAP_LOG family of macros specifically for errors that occur |
| // while interoperating with the bootstrap subsystem. These errors will first |
| // be looked up as bootstrap error messages. If no match is found, they will |
| // be treated as generic Mach errors, as in MACH_LOG. |
| // |
| // Examples: |
| // |
| // kern_return_t kr = mach_timebase_info(&info); |
| // if (kr != KERN_SUCCESS) { |
| // MACH_LOG(ERROR, kr) << "mach_timebase_info"; |
| // } |
| // |
| // kr = vm_deallocate(task, address, size); |
| // MACH_DCHECK(kr == KERN_SUCCESS, kr) << "vm_deallocate"; |
