Detailed Description

Function Documentation

int ay_checkversion	(	char *	fname,
		char *	version_ma,
		char *	version_mi
	)

compare plugin compilation and Ayam runtime versions

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.

Parameters:

`[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

Returns:: AY_OK if the plugin version is compatible, AY_ERROR if the plugin version is not compatible, AY_ENULL if any version parameter is NULL
