QlgRmdir()--Remove Directory (using NLS-enabled path name)

 #include <unistd.h>

 int QlgRmdir(Qlg_Path_Name_T *path,);  

The QlgRmdir() function, like the rmdir() function, removes a directory, path, provided that the directory is empty; that is, the directory contains no entries other than "dot" (.) or "dot-dot" (..). The difference is that the QlgRmdir() function takes a pointer to a Qlg_Path_Name_T structure, while rmdir() takes a pointer to a character string.

Limited information on the path parameter is provided here. For more information on the path parameter and for a discussion of authorities required, return values, usage notes, and related information, see rmdir()--Remove Directory.

Parameters

path

(Input) A pointer to a Qlg_Path_Name_T structure that contains a path name or a pointer to a path name of the directory to be removed. For more information on the Qlg_Path_Name_T structure, see Path name format.
