Initiation of the programme



  • Could the launch be further replicated during the programme? For example, my program needs to process a big data file. What's best to do, start grep a separate process, and how to obtain exit data (which I do not understand so far) or to co-compil a library with a real f-l grepHuh?



  • The launch is, of course, possible. That's what many GUI programmes do. You choose what's best. If the speed of work and the memory flow is not so principled, but more importantly, the reliability and speed of development, another application may be launched and considered to be its conclusion. If you need it to work fast, it's better to either write the code itself or use the existing libraries, just connect them. Existing applications can be viewed as such as the required functionality.

    The conclusion of the subsidiary process can be read either through the function popen() or low-level systemic pipe and dup2.
