Determines if a file's registered content type matches the specified content type. This function obtains the content type for the specified file type and compares that string with the pszContentType. The comparison is not case-sensitive.


BOOL PathIsContentTypeW(
  [in] LPCWSTR pszPath,
  [in] LPCWSTR pszContentType


[in] pszPath


A pointer to a null-terminated string of maximum length MAX_PATH that contains the file whose content type will be compared.

[in] pszContentType

Return value

Type: BOOL

Returns nonzero if the file's registered content type matches pszContentType, or zero otherwise.



The shlwapi.h header defines PathIsContentType as an alias which 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 not encoding-neutral can lead to mismatches that result in compilation or runtime errors.
