/*
 * EFerr.c -
 *
 *	Contains only the routine efReadError().  This used to be in EFread.c,
 *	but including Tcl/Tk stuff caused definition conflicts.  So now it
 *	gets its own file.  Note that *printf routines have been changed to
 *	the Tx* print routines for compatibility with the Tcl-based version.
 *	Note also that the standalone executables ext2sim and ext2spice get
 *	the Tx* functions from utils/LIBtextio.c, whereas the built-in
 *	"extract" function gets them from textio/txOutput.c.  In the Tcl
 *	version, all these functions are built in, so utils/LIBtextio.c is
 *	not compiled or linked.
