 314  506  This function is not provided for the purpose of enabling utilities to perform
 315  507  path name expansion on their arguments, as this operation is performed by the
 316  508  shell, and utilities are explicitly not expected to redo this. Instead, it is
 317  509  provided for applications that need to do path name expansion on strings
 318  510  obtained from other sources, such as a pattern typed by a user or read from a
 319  511  file.
