The ServerModule symbol

The ServerModule symbol resolves to a server_module_t type, which is a data structure defined in server_module.h from libserver:

typedef struct _server_module_t {
        char            *name;
        char            *description;
        int             ver_major, ver_minor, ver_micro;
        int             build_ver_major, build_ver_minor, build_ver_micro;
        char            **authors;
        cfg_opt_t       *configuration\_options;
        int             (*construct)(void *);
        int             (*prestart)(cfg_t *);
        void *          (*operator)(void *);
        void            (*report)(FILE *);
} server_module_t;
