I'm trying to do this:
mbx.km_version=KSE_VER_0;
mbx.km_func=uc_1;
mbx.km_stack.ss_sp=stack_1;
mbx.km_stack.ss_size=SIGSTKSZ;
mbx.km_stack.ss_flags=SS_ONSTACK;
ret=getcontext(&(thr_mbx.tm_context));
printf("getcontext %d\n",ret);
thr_mbx.tm_context.uc_link=NULL;
thr_mbx.tm_context.uc_stack.ss_sp=thr_stack_1;
thr_mbx.tm_context.uc_stack.ss_size=SIGSTKSZ;
thr_mbx.tm_context.uc_stack.ss_flags=SS_ONSTACK;
makecontext(&(thr_mbx.tm_context),func,0);
thr_mbx.tm_uticks=10;
thr_mbx.tm_sticks=0;
mbx.km_curthread=&thr_mbx;
ret=kse_create(&mbx,0);
do
{
++i;
}while(1);
And never got upcall. (But if I put printf in the loop I got the
upcall).
Thanks,
Sergey.
