There is a branch of JOE which uses co-routines: http://sourceforge.net/p/joe-editor/mercurial/ci/default/tree/docs/hacking.md http://sourceforge.net/p/joe-editor/mercurial/ci/default/tre... The main release doesn't use them yet, but the Windows port does. My co-routine library also allows arbitrary arguments, but it just uses va_list for this. Also I use setjmp/longjump and stack allocations (if ucontext is not available), but do not depend on c99 dynamic arrays to do it. BTW, the array trick doesn't work on some architectures: IA64 (there are two stacks) or Cray (the stack is a linked-list).
