MgErr FDirName(path, dir);

Purpose

Creates a path for the parent directory of a specified path. You can pass the same path variable for the parent path that you use for path. Therefore, you can call this function in the following two ways:

  • err = FDirName(path, dir);/* the parent path is returned in a second path variable */
  • err = FDirName(path, path);/* the parent path writes over the existing path */

Parameters

Name Type Description
path Path Path whose parent path you want to determine.
dir Path Parameter in which FDirName stores the parent path.

Return Value
