Send Return Code back from child script to the Parent script

Question

My child script can create a rc=110 when a FTPed file is not located. The Parent script sets the Error Handling RC=1. I want the Error Handling to set to the RC created in child script. Any ideas?

Answer 1

What operating system? In linux you can forward the paramenter using standard input/output using the | (pipe)

./script | ./binaryName

This forwards the output of ./script as the input of ./binaryName and in your main:

int main(int argc, char **argv){
//Don't use argv[0]!
char* yourOutput = argv[1];
return 0;
}

I just realized your "parent" is a script too. Which language is this? All the languages I've worked with have a manner to get arguements like I just showed you in C++.
