//// STRUCTUREAPI.EPOCH//// Simple demonstration of how to use structure (record) types with external APIs//structure msgboxtype :( integer(size), integer(ownerwnd), integer(instance), string(text), string(caption), integer(style), string(icon), integer(helpid), integer(callback), integer(language) )structure systeminfotype :( integer16(architecture), integer16(reserved), integer(pagesize), integer(minappaddress), integer(maxappaddress), integer(activeprocmask), integer(numprocessors), integer(proctype), integer(allocgranularity), integer16(proclevel), integer16(procrevision))external "user32.dll" MessageBoxIndirectW : (msgboxtype(params)) -> (integer)external "kernel32.dll" GetSystemInfo : (systeminfotype ref(info)) -> ()entrypoint : () -> (){ systeminfotype(info, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0) GetSystemInfo(info) string(proccountstr, "") assign(proccountstr, concat("System processor count: ", cast(string, readstructure(info, numprocessors)))) integer(styleflags, 64) msgboxtype(params, sizeof(msgboxtype), 0, 0, proccountstr, "Epoch test", styleflags, "", 0, 0, 0) MessageBoxIndirectW(params)}Woot.
Of course, simpler programs that use reference parameters also work:
entrypoint : () -> (){ integer(foo, 0) increment(foo) debugwritestring(cast(string, foo))}increment : (integer ref(value)) -> (){ assign(value, add(value, 1))}All in all, a happy improvement to the system.
