At the end of sunplay.c there's the comment: /* #### sigcontext doesn't exist in Solaris. This should be updated to be correct for Solaris. */ static SIGTYPE sighandler (int sig) { The sigcontext for Solaris is actually called ucontext (in ucontext.h). And signal handlers are passed something like: handler(int signal, siginfo_t *code, struct ucontext *context) What is supposed to happen in sunplay with the sigcontext? Should all of these parameters in sighandler get passed on to sighup_handler and sigint_handler? Ray
