User dir

Hi all. How would i go about making a prog that would make a dir in the home dir for linux with out knowing what the user name is? For example, if i have /home/someguy/ as a file path, how would i write that in some code?

Code example

Code:

---

char buffer="mkdir /home/";
system(buffer);

---

Does that make sense? If not let me know so i can elaborate. Thanx in advance!

Anyone? Isnt there a function to look up the file path of the current user? Like Windows GetDirectory() API ? .....

In unistd.h there is a function called getcwd() that gets the current working directory.

You can use getenv (in stdlib.h) to get the HOME environment variable, which is by default /home/username/:

Code:

---

cout <<getenv("HOME") <<endl; //outputs "/home/rob" - my name is rob
