Would it be more robust to use a lookup table for the overridable value types?
static const
struct {
OverridableDataType o_type;
size_t o_offset;
} overridable[] = {
/* TS_CONFIG_URL_REMAP_PRISTINE_HOST_HDR */
{ OVERRIDABLE_TYPE_BYTE, offsetof(OverridableHttpConfigParams,
maintain_pristine_host_hdr},
...
};
void*
_conf_to_memberp(TSOverridableConfigKey conf, HttpSM* sm, OverridableDataType
*typep)
{
*typep = overridable[conf].o_type;
return ((uint8_t *)(sm->t_state.txn_conf)) + overridable[conf].o_offset;
}
