Hello Fans!
Still need help with Rendez...
I can use lock, qlock and rendezvous without any problem but Rendez
don't work... if rsleep executed earlier than rwakeup, abort() cause
exception, stk() show:
rsleep ... /sys/src/libc/9sys/qlock.c:286
This line contain me = getqlp() in getqlp i find abort()...
in other way when rwakeup executed first, abort() ... stk() show:
rwakeup ... /sys/src/libc/9sys/qlock.c:329
which point me to another abort()
Maybe it wrong initialization? But I also try other way... or I wrong
use rendez?
#include <u.h>
#include <libc.h>
QLock q={0};
Rendez r={.l=&q};
void testthread(void)
{
switch(rfork(RFPROC|RFMEM))
{
case -1:
print("can't fork");
exits(0);
case 0:
break;
default:
return;
}
for(;;)
{
print("Sleep\n");
rsleep(&r);
print("Wake up!\n");
}
exits(0);
}
void main(int,char**)
{
int x;
testthread();
for (x=0;x<10;)
{
if (rwakeup(&r))
x++;
}
exits(0);
}
Thanks for help!
