May report incompatibility to the user via ay_error().
If this function returns AY_ERROR, plugin loading should be aborted immediately as crashes will likely occur should the plugin attempt to use the (incompatible/changed) Ayam API.
[in] | fname | place parameter for ay_error(), may be NULL |
[in] | version_ma | major Ayam version the plugin was compiled with |
[in] | version_mi | minor Ayam version the plugin was compiled with |
