Comments

Use CzFunc wrapper

It is strongly recommended that developers use the CzFunc wrapper in preference to the API zeofunc_ methods. CzFunc automates some of the labour in dealing with argument prototype lists and return value handling.

Thread safety

zeofunc_Execute2 is a threadsafe version of zeofunc_Execute, which used a common return variable for all function calls, including parallel calls from different threads. zeofunc_Execute2 should alwyas be used in preference to zeofunc_Execute.
