_fullpath vs GetFullPathName

What is the difference between: _fullpath and GetFullPathName

Of course I mean compare their ANSI/Unicode variants separatly

It seems that _fullpath has much nicer and simpler API as it allows to allocate the buffer for you but I just think if I replace GetFullPathNameW with _wfullpath what would I miss?

You wouldn't necessary miss anything. In fact, it's quite possible that _fullpath() calls GetFullPathName(). In that case, _fullpath() works like a sort of wrapper for GetFullPathName(), which would explain why the interface seems a little simpler and easier to use.

You simply have multiple ways to accomplish the same task. And, as long as either method is not obsolete and performs the task needed, the choice is entirely up to you.

_fullpath is part of the C library. GetFullPathName is a Win32 API.

So basically, _fullpath is cross platform and GetFullPathName is Windows-specific.

In such cases, the C function usually relies on the underlying OS. So, in a Windows program, _fullpath most likely boils down to GetFullPathName(). But you don't have to care really.
