PathCchRemoveBackslash function

Removes the trailing backslash from the end of a path string.

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

Syntax

HRESULT PathCchRemoveBackslash(
  _Inout_ PWSTR  pszPath,
  _In_    size_t cchPath
);

Parameters

pszPath [in, out]

A pointer to the path string. When this function returns successfully, the string contains the path with any trailing backslash removed. If no trailing backslash was found, the string is unchanged.

cchPath [in]

The size of the buffer pointed to by pszPath, in characters.

Return value

This function returns S_OK if the function was successful, S_FALSE if the string was a root path or if no backslash was found, or an error code otherwise.

Remarks

This function will not remove the backslash from a root path string, such as "C:\".
