Title: SAVE-IMAGE and :RESTART-FUNCTION
ID: 16008
| Product: LispWorks Version: All OS: All | |
| Description: Consider: (SAVE-IMAGE "my-image" :restart-function 'my-restart ) When my-image runs, it calls MY-RESTART before multiprocessing starts, hence the function MY-RESTART must not rely on multiprocessing. You can however use MY-RESTART to tell the image to do something when multiprocessing starts up, e.g. (defun my-restart () (push '("initialize" nil my-initialization-function) mp:*initial-processes*)) If MY-RESTART returns, then normal startup, as in the original image, follows. You need the patch run-first-top-level-p-hook (:SYSTEM patch sequence, patch level 4.1.19) for this on Windows and Linux. If you are simply looking for where to add an initialization routine, then it is simpler to add it to one of the existing action lists "When starting image", "Upon Starting Environment" or "Initialize LispWorks Tools". See Knowledgebase item "Action Lists". | |
