C/C++ - Locating a user's home directory - SOLVED

[David Fletcher]

//	For the benefit of anybody else who searches Google
//	to try to find an answer to this question:-

//	Short example
//	how to write a C/C++ program for Linux to determine
//	find the home directory of the user who is running it

//	Use the command
//	g++ -Wall HomeDirTest.cpp -o HomeDirTest
//	to compile this source

//	Compiled and tested by running as a cron job on an
//	Ubuntu 10.04 server with the executable file copied
//	to /usr/local/bin/
