[ksh93+] Array fed by function is empty when used in main.
I feel that i am missing something obvious but i can't find what is wrong.
I have a script that is launching some functions with "&" and each call is feeding the array with a value. When all calls are finished I just want to retrieve the values of that array.
i just finished a project for a c++ class that i wrote at home on my computer, compiled with gcc. when i brought the code into school it would not compile, it would complain that cannot call main() function. at school we use ancient borland c++ from 1995. anyway my program has 20 different...

I wrote a script in ksh93 (the OS is AIX 5.2, ML7), which failed to run. After some testing i found out why, but the answer is a bit dissatisfying. Look for yourself:

Hi,
I have a main loop which calls a sub loop, which finally returns to the main loop itself. The main loop runs when a flag is set. Now, I have a signal handler for SIGINT, which resets the flag and thus stops the main loop. Suppose I send SIGINT while the program is in subloop, I get an error... (1 Reply)

H friends,
As we know, a function returns a value and that value is saved somwhere. like
int Sum( int x, int y )
{
return x + y;
}
Total = Sum( 10, 20 );
The value 30 is saved in variable Total.
Now the question is, what int value does the function main return, and where is it... (5 Replies)
A sample.c file is written with only one single statement.
main;
Segmentation fault occurred when executed that file.
Any statement other than main; is written, for example unix; then it won't compile.
why is this behaviour ! (2 Replies)
Hi Experts,
I have several shell scripts that have been developed on a Linux box for korn ksh93.
If we want to run this software on an AIX 6.1 box that runs ksh88 by default can we just change the she-bang line to reference /bin/ksh93 which ships with AIX as its "enhanced shell" to ensure... (6 Replies)

int pcntl_sigwaitinfo (array $set, [array &$siginfo])
DESCRIPTION
The pcntl_sigwaitinfo(3) function suspends execution of the calling script until one of the signals given in $set are delivered. If one of
the signal is already pending (e.g. blocked by pcntl_sigprocmask(3)), pcntl_sigwaitinfo(3) will return immediately.

o $set
- Array of signals to wait for.
o $siginfo
- The $siginfo parameter is set to an array containing informations about the signal. The following elements are set for all sig-
nals:
osigno: Signal number
oerrno: An error number
ocode: Signal code
The following elements may be set for the SIGCHLD signal:
ostatus: Exit value or signal
outime: User time consumed
ostime: System time consumed
opid: Sending process ID
ouid: Real user ID of sending process
The following elements may be set for the SIGILL, SIGFPE, SIGSEGV and SIGBUS signals:
oaddr: Memory location which caused fault
The following element may be set for the SIGPOLL signal:
oband: Band event
ofd: File descriptor number
RETURN VALUES
On success, pcntl_sigwaitinfo(3) returns a signal number.
EXAMPLES
Example #1
pcntl_sigwaitinfo(3) example
<?php
echo "Blocking SIGHUP signal
";
pcntl_sigprocmask(SIG_BLOCK, array(SIGHUP));
echo "Sending SIGHUP to self

posix_kill(posix_getpid(), SIGHUP);
echo "Waiting for signals
";
$info = array();
pcntl_sigwaitinfo(array(SIGHUP), $info);
?>
