sway commands are implemented using functions that return an error code and (if the function was not successful) an error string. The two are bundled together by the type `struct cmd_results`. This patch alters the command handler prototype so that the cmd_results objects are returned by value (on the stack), instead of by a pointer to a heap allocated instance of a cmd_results. The latter method had the flaw that, if the heap allocation of the cmd_results object failed, the exact return code would be lost. Furthermore, for some command handlers (such as those in sway/commands/output), returning NULL signified success, so an allocation failure could lead to an ignored error. This change prevents both classes of errors. |
