adaptor_info
structure is used to pass adaptor info (duh) back to the
config module when it's building an adaptor instance. Here's what it contains:
static char *names[] = { "init", "free", "info", "get", "auth" }; XML * USER_localxml_init (WFTK_ADAPTOR * ad, va_list args); XML * USER_localxml_free (WFTK_ADAPTOR * ad, va_list args); XML * USER_localxml_info (WFTK_ADAPTOR * ad, va_list args); XML * USER_localxml_get (WFTK_ADAPTOR * ad, va_list args); XML * USER_localxml_auth (WFTK_ADAPTOR * ad, va_list args); static WFTK_API_FUNC vtab[] = { USER_localxml_init, USER_localxml_free, USER_localxml_info, USER_localxml_get, USER_localxml_auth }; static struct adaptor_info _USER_localxml_info = { 5, names, vtab }; |
