1998-04-21 19:05 Ulrich Drepper <drepper@cygnus.com> * iconv/gconv.h (struct gconv_step): Add element stateful. * iconv/gconv_builtin.c (__gconv_builtin_trans): Initialize stateful to zero for all internal conversions. * iconv/skeleton.c: Initialize stateful depending on whether or not RESET_STATE is defined to one or zero respectively. * stdlib/mblen.c: Use stateful element of currently selected converter for result if S is NULL. * stdlib/mbtowc.c: Likewise. * stdlib/wctomb.c: Likewise.
