In CW 68K files, 1) all of the constructors from a source file are called from a single block of code that's output as an "__InitCode__" symbol. 2) the linker combines all of these into one long function called __InitCode__ which gets called by the runtime. 3) as constructors are called by __InitCode__, references to the destructors of objects are passed to __register_global_object, which will let the routine __destroy_global_chain call destructors in reverse order at application exit. Look in PalmOS_GlobalDestructors.c and PalmOS_Startup.cpp for details, especially the comment before __InitCode__. GCC's method for startup has little resemblance to CodeWarrior. ------------------ Ok thanks a lot Ben :) -- For information on using the PalmSource Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
