[ECOS] (Is main() a normal thread ?) problem was my fault...

[Claudio Leonel <cls at elaxys dot com dot br>]

Hi,

I found the problem why the following program
does not work as intended:
------------------------------------------------
int main(void) {
   while (1) {
      cyg_thread_delay(100);
   }
}
------------------------------------------------

It will work if the header file <cyg/kernel/kapi.h>
is included.

The reason is that the parameter of cyg_thread_delay()
is a 64 bit variable. Without the header file, the compiler
will pass a 32 bit variable and the most significant word
is undefined, and could be a huge value,
so cyg_thread_delay() will delay for much more than 100 ticks...

The problem had nothing to do with main(). In my other
test program which used cyg_user_start() and another
thread, the header file was included, so the problem
didn't occur...

The moral of the story for me is:
  Allways include the header files !!!

Claudio L. Salvadori
