Is there a function in c++ for retriving the applications path?

argv[0] and GetModuleFileName(0).

char *_getcwd( char *buffer, int maxlen );

_getcwd (get current working directory) will NOT always be the path where your app resides in.

Imagine starting an exe from dos-box like this:

c:\program files\>d:\yourapp.exe

argv[0] or GetModuleFileName(0) is your way to go, but you have to strip the filename of your app from the string.

Ah, but it''s possible that argv[0] is empty (I had this last week when trying to insert a custom executable into a make process.) I''m not certain of exactly when it''s empty (I couldn''t really be bothered checking) but I think calling an exe through a batch process might result in an empty argv[0].

Also, GetModuleFileName(0) is a Windows call. The original poster didn''t specify an operating system.

IIRC, argv[0] isn''t required to include the full path to the executable.
