Callback Test Suite ------------------- CONFIGURE SUITE needs lua: edit config.lua and run "make config". DESCRIPTION Generates a set of callback invokers in C using lua as a preprocessor. The invokers pass random arguments to the callback to test, from a set of reference values which are argument type- and position-specific. The Callback Invocation Body Example: The body for a signature of type "dpdf)p" at case id 19 is: void f19(void* addr) { V_p[4] = ((p(*)(d,p,d,f))addr)(K_d[0],K_p[1],K_d[2],K_f[3]); } ^^^^- dyncallback object ^^^^^^^^^^^^^- signature ^- return type ^- args from reference values (to be retrieved in handler) The K_? values are the reference values, which are supposed to be copied to V_?, and are compared for identity after invocation. The arguments are copied to V_? in the callback handler, called through "addr". The reference values stored in K_? are generated once, randomly, at startup. Specific calling conventions: Specify 'api' and 'ccprefix' accordingly to generate callbacks for a specific/custom calling convention: "__stdcall" "_s" "__fastcall" "_f" for gcc compiler "_F" for microsoft compiler See the dyncall documentation for other/more calling convention prefixes.
