PENUMDIRTREE_CALLBACKW callback function

-description

An application-defined callback function used with the EnumDirTree function. It is called every time a match is found.

The PENUMDIRTREE_CALLBACK and PENUMDIRTREE_CALLBACKW types define a pointer to this callback function. EnumDirTreeProc is a placeholder for the application-defined function name.

-parameters

-param FilePath [in]

A pointer to a buffer that receives the full path of the file that is found.

-param CallerData [in, optional]

A user-defined value specified in EnumDirTree, or NULL. Typically, this parameter is used by an application to pass a pointer to a data structure that enables the callback function to establish some context.

-returns

To continue enumeration, the callback function must return FALSE.

To stop enumeration, the callback function must return TRUE.

-remarks

Note

The dbghelp.h header defines PENUMDIRTREE_CALLBACK 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. For more information, see Conventions for Function Prototypes.
