About VOID, RUN_ALL and RUN_FIRST

  • VOID ・・・ Implement a hook that has no return code, and therefore runs all of the registered functions.

  • RUN_ALL ・・・ Implement a hook that runs until one of the functions returns something other than OK or DECLINE.

  • RUN_FIRST ・・・ Implement a hook that runs until the first function returns something other than the value of decline.
