Hi, I am trying to run three different tasks, with the "execi" command. When all of the have the same priority=10, everything works ok. When I change the priority in one of them priority=11 or 12, then everything seems to go much slower, and (...) (24 years ago, 21-Feb-01, to lugnet.robotics.rcx.legos)

(...) In C you should call execi() like this: execi(controlThread, 0, NULL, 2, DEFAULT_STACK_SIZE); /* Removed `&' */ since a function is like an array name: it is an address. Probably the same applies to C++. bye Bernardo (24 years ago, 18-Feb-01, to lugnet.robotics.rcx.legos)
