dbd does this: APR_REGISTER_OPTIONAL_FN(ap_dbd_prepare); APR_REGISTER_OPTIONAL_FN(ap_dbd_open); APR_REGISTER_OPTIONAL_FN(ap_dbd_close); APR_REGISTER_OPTIONAL_FN(ap_dbd_acquire); APR_REGISTER_OPTIONAL_FN(ap_dbd_cacquire); APR_RETRIEVE_OPTIONAL_FN(one of the functions above) should give you NULL if DBD is absent. The two macros are declared in apr_optional.h. S -- A: Because it reverses the logical flow of conversation. Q: Why is top-posting frowned upon? A: Top-posting.
