PathCchRemoveExtension function (pathcch.h)

  • Article

Removes the file name extension from a path, if one is present.

This function differs from PathRemoveExtension in that it accepts paths with "\", "\?" and "\?\UNC" prefixes.

NoteThis function, should be used in place of PathRemoveExtension to prevent the possibility of a buffer overrun.
