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

MgErr, which can contain the following errors. If you receive errors from CIN functions, most error names correspond to LabVIEW error codes.

Value	Corresponding Error Code or Description
noErr	No error.
mgArgErr	1
