PathCchAddBackslash function (pathcch.h)

  • Article

Adds a backslash to the end of a string to create the correct syntax for a path. If the source path already has a trailing backslash, no backslash will be added.

This function differs from PathCchAddBackslashEx in that you are restricted to a final path of length MAX_PATH.

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

Note  This function, or PathCchAddBackslashEx, should be used in place of PathAddBackslash to prevent the possibility of a buffer overrun.

Syntax

WINPATHCCHAPI HRESULT PathCchAddBackslash(
  [in, out] PWSTR  pszPath,
  [in]      size_t cchPath
);

Parameters

[in, out] pszPath

A pointer to the path string. When this function returns successfully, the buffer contains the string with the appended backslash. This value should not be NULL.

[in] cchPath

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 path string already ends in a backslash, or an error code otherwise.
