Hello everybody,
I'm using fork with a simple application, and it looks like if the
father process continues executing without waiting his child, the
following is the code that i use:
my $redirected=1;
my $pid=fork();
if($pid == 0){ #this the child
my @output=`date`;
$Vocp->log_msg("THIS IS THE
CHILD WHICH \$pid IS $pid>>>>@output");
my $redirected=$Vocp->dial(32);
$Vocp->log_msg("REDIRECTION
DONE, AND \$redirected is
$redirected\n");
exit(0);
}elsif($pid != 0){
wait;
my @output=`date`;
$Vocp->log_msg("THIS IS THE
FATHER AND \$pid is $pid>>>@output\n");
}else{
$Vocp->log_msg("I DON'T KNOW
WAHT THE HELL IS GOING UP HERE !!!!!!!!!!!\n");
}
$vocp->log_msg is method to write a message to estandard error (which
was previously redirected to a file)
$vocp->dial() it makes a call to a phone
the output error file is
/etc/mgetty+sendfax/vocp/vocp.pl.st.trans [2403]: Redirection could go
for 032, which is command box in VOCP=HASH(0x811893c)
/etc/mgetty+sendfax/vocp/vocp.pl.st.trans [2403]: Redirection certainly
goes for 032 which is command in VOCP=HASH(0x811893c)
/etc/mgetty+sendfax/vocp/vocp.pl.st.trans [2463]: THIS IS THE CHILD
WHICH $pid IS 0>>>Mon Jun 4 13:58:36 CDT 2001
@@@@@@@ here is the problem the father is writting before the child
ends

i was expecting something like, dialout then disconected, etc..
am i well debugging the system?, or is there another way?
does someone have any idea about this?
thanks for all.
