Where is getopt

[lostbits]

Does anyone know where to find getopt?

getopt is in the header <unistd>, or if you want to use getopt_long its in the header <getopt.h>

that is a link to a small tutorial on how to use getopt, if you need one

In the non-standard <unistd.h> C header. Not every compiler has it, Visual Studio doesn't.

At the moment, I am using Visual Studio (only because Netbeans 12.4 seems to be having difficulty with C/C++). So, <unistd.h> is not available nor is <getop.h>.

if you google it, there are some workarounds ready to download.

this is a bit simpler than the original getopt, but depending on how you work with it, it might be enough.
