Hi guys,
Is there any way that my module can detect which APR features are
enabled in Apache? It relies on DBD, and if that's not available then my
module just segfaults, which isn't very friendly. I'd prefer to give an
error message to the user, telling them that DBD is required.
Does anyone have any tips, or should I ask the APR list instead?
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.
Thanks Sorin -- just what I was after!
Dave
