How can I assign “pwd” (or any other command in that case) result (present working dir) to a variable which is char*?
command can be anything. Not bounded to just “pwd”.
Thanks.

Start with
popen. That will let you run a command with its standard output directed to aFILE *that your parent can read. From there it’s just a matter of reading its output like you would any normal file (e.g., withfgets,getchar, etc.)Generally, however, you’d prefer to avoid running an external program for that — you should have
getcwdavailable, which will give the same result much more directly.
