Anyway, as I said, a placeholder now fixes that.
Out of curiosity, is there any reason we can't just forward declare the
struct and access the internals via some accessor functions?
Hmmm, fair point.
There's one definite stumbling block there: the varargs APIs.
Can the vararg functions (specifically, the pvquery and pvselect
functions) be expressed as apr_dbd #defines, like the rest of
the calls? Anyone?
Why does that matter? My suggestion doesn't involve any wrapper
defines, just functions...
in apr_dbd.h:
typedef struct apr_dbd_driver_t apr_dbd_driver_t;
apr_status_t apr_dbd_func_that_takes_varargs(apr_dbd_driver_t *d, ...);
in driver.c
struct apr_dbd_driver_t {
/* stuff */
};
apr_status_t apr_dbd_func_that_takes_varargs(apr_dbd_driver_t *d, ...)
{
// turn ... into va_list
return d->func(my_va_list);
}
I don't see the need for the macros at all...
