| |
Hello!
Currently I do not open /dev/console in cinit, but currently I do see very strange behaviour:
If the first printf() in the following code (from serv/cinit.c) is enabled, the socket communication will later fail:
---------------------------------------------------------------------- #ifdef DEBUG // printf("ARGC=%d\n",argc); #endif
set_signals(ACT_SERV); /* set signal handlers */ #ifdef DEBUG printf("ARGC=%d\n",argc); #endif ----------------------------------------------------------------------
I don't know what could be the relation between this printf and the behaviour that cinit-0.1 later hangs in comm/do_result when reading the resulting byte from a socket.
If you want to see the full code, it can be found at [0].
This code contains serv/cinit.c, which is the same as found in cinit-0.0.8 [1] and serv/cinit.c-cinit0.1, which is the one with a bit more debugging and the printf() before set_signals, which makes cinit hang in comm/do_result at the position when fpoint() is called.
Perhaps this is an issue with not opening /dev/console? It's just a guess, because I don't have any idea what could cause this behaviour.
If someone has _any_ idea, I would be very thankful.
Nico
