Creates a root path from a given drive number.

Syntax

LPWSTR PathBuildRootW(
  [out] LPWSTR pszRoot,
  [in]  int    iDrive
);

Parameters

[out] pszRoot

Type: LPTSTR

A pointer to the string that receives the constructed root path. This buffer must be at least four characters in size.

[in] iDrive

Type: int

A variable of type int that indicates the desired drive number. It should be between 0 and 25.

Remarks

Note

The shlwapi.h header defines PathBuildRoot 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.
