I'd think about why it's necessary to run that program as setuid root, and if that couldn't be accomplished by other means (eg. sudo) or by using a different approach using as few privileges as possible.
IF that isn't possible, you could simulate the system() call by using fork() and wait() (warning: the following is pseudo-code)

hi there,
i was reading about the exec() function. and if i m not wrong, exec() kills your present process and starts a new process in its place. the process id remains the same.

Hello World!
I am writing code in C++ which have to launch another application X using exec().
I would like to set some limits on it using setrlimit etc...
My problem is that i don't know how to forbid using fork() and strlimit by application X.
How can i do it? (3 Replies)
I can't get this to work. Running a single command works fine:
find . -name "*.dat" -exec wc -l '{}' \;
gives me the file name and number of lines in each .dat file in the directory.
But what if I want to pipe commands, e.g. to grep something and get the number of lines with that pattern... (3 Replies)
Hi again ;) Now I want to make a program that will execute the programs with exec, asking the user if he wants the program to run in background or foreground.

Hi,
I have coded a program in Haskell using the compiler Hugs and the program requires multiple commands (with parameters) to be entered into it, it then outputs the result of its execution. I need to test a lot of different options (i.e. the parameters) so it would be obvious to automate the... (0 Replies)

wait
WAIT(1) BSD General Commands Manual WAIT(1)NAME
wait -- await process completion
SYNOPSIS
wait [pid]
DESCRIPTION
If invoked with no arguments, the wait utility waits until all existing child processes in the background have terminated.
Available operands:
pid If a pid operand is specified, and it is the process ID of a background child process that still exists, the wait utility waits until
that process has completed and consumes its status information, without consuming the status information of any other process.
If a pid operand is specified that is not the process ID of a child background process that still exists, wait exits without waiting
for any processes to complete.
The wait utility exits with one of the following values:
0 The wait utility was invoked with no operands and all of the existing background child processes have terminated, or the process
specified by the pid operand exited normally with 0 as its exit status.
>0 The specified process did not exist and its exit status information was not available, or the specified process existed or its exit
status information was available, and it terminated with a non-zero exit status.
If the specified process terminated abnormally due to the receipt of a signal, the exit status information of wait contains that termination
status as well.
STANDARDS
The wait command is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
