How do I resolve a relative path to an absolute path in C?

问题

I have a C console app where I need to output the absolute path to a file given a (possibly) relative path. What is the best way to do this in C in a Windows environment?

回答1:

I think you are looking for _fullpath().

回答2:

GetFullPathName should help you on Windows.

GetFullPathName merges the name of the current drive and directory with a specified file name to determine the full path and file name of a specified file.
