Set environment variables in C

Question

Is there a way to set environment variables in Linux using C?

I tried setenv() and putenv(), but they don\'t seem to be working for me.

Answer 1

The environment variable set by setenv()/putenv() will be set for the process that executed these functions and will be inherited by the processes launched by it. However, it will not be broadcasted into the shell that executed your program.

Why isn't my wrapper around setenv() working?
