If it is not null then an environment path is found. If I compile the sample then the output on a Windows 7 system is: The set path is: C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\ImageConverter Plus\Microsoft.VC90.CRT;C:\Program Files (x86)\ImageConverter Plus\Microsoft.VC90.MFC;C:\Program Files (x86)\QuickTime\QTSystem\;C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static So the example works. I hope that this helps you. @sivaraman – That is not correct, if null is returned then no environment path is found. If it is not null then an environment path is found.

SO it will return NULL. Please explain a case in which getenv() is
