1 /* Simple implementation of vsprintf for systems without it. 2 Highly system-dependent, but should work on most "traditional" 3 implementations of stdio; newer ones should already have vsprintf. 4 Written by Per Bothner of Cygnus Support. 5 Based on libg++'s "form" (written by Doug Lea; dl@rocky.oswego.edu). 6 Copyright (C) 1991, 1995, 2002 Free Software Foundation, Inc. 7 8 This file is part of the libiberty library.
