void cleanup (  show_status   )

Referenced by dbops_func().

int fix_cfg_file (  void   )

Update cfg_file variable to contain full pathname. The function updates the value of cfg_file global variable to contain full absolute pathname to the main configuration file of SER. The function uses CFG_FILE macro to determine the default path to the configuration file if the user did not specify one using the command line option. If cfg_file contains an absolute pathname then it is used unmodified, if it contains a relative pathanme than the value returned by getcwd function will be added at the beginning. This function must be run before SER changes its current working directory to / (in daemon mode). Returns: Zero on success, negative number on error. Definition at line 1055 of file main.c.
