Syntax

LPCWSTR PathFindExtensionW(
  [in] LPCWSTR pszPath

Note

The shlwapi.h header defines PathFindExtension as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
