2002-08-04 Jakub Jelinek <jakub@redhat.com> * manual/debug.texi: Fix spelling to programmatically. Reported by <hayastan132@hotmail.com>. * include/libio.h: Add libc_hidden_proto for __uflow. * include/stdio.h: Map fopen, fdopen, fclose, fputs, fsetpos, and fgetpos to _IO_* names. Add libc_hidden_proto for fileno, fwrite, fseek, fflush_unlocked, fread_unlocked, fwrite_unlocked, fgets_unlocked, fputs_unlocked. * include/wchar.h: Add libc_hidden_proto for fputws_unlocked, putwc_unlocked, vswscanf. * libio/iolibio.h: Add libc_hidden_proto for _IO_fputs. * libio/fileno.c: Use <stdio.h> and libc_hidden_def. * libio/fseek.c: Likewise. * libio/fmemopen.c: Include "libioP.h". Call _IO_fopencookie and not fopencookie. * libio/genops.c (__uflow): Add libc_hidden_def. * libio/iofflush_u.c (fflush_unlocked): Likewise. * libio/iofgets_u.c (fgets_unlocked): Likewise. * libio/iofputs_u.c (fputs_unlocked): Likewise. * libio/iofputws_u.c (fputws_unlocked): Likewise. * libio/iofread_u.c (fread_unlocked): Likewise. * libio/iofwrite_u.c (fwrite_unlocked): Likewise. * libio/iovswscanf.c (vswscanf): Likewise. * libio/putwc_u.c (putwc_unlocked): Likewise. * libio/iofputs.c: Use libc_hidden_def instead of INTDEF. * malloc/malloc.c: Redirect fwrite calls to _IO_fwrite. * malloc/mtrace.c: Likewise. * sunrpc/clnt_perr.c: Remove fputs macro. * sunrpc/svc_simple.c: Likewise. * sunrpc/svc_tcp.c: Likewise. * sunrpc/svc_udp.c: Likewise. * sunrpc/xdr_rec.c: Likewise. * sunrpc/xdr_ref.c: Likewise. * iconv/Makefile: Add CPPFLAGS definitions with -DNOT_in_libc for iconv_prog, linereader, and charmap-dir. * locale/Makefile: Likewise for locale and charmap-dir. * malloc/Makefile: Likewise for memusagestat. * nscd/Makefile: Likewise for nscd, nscd_conf, and dbg_log. * sunrpc/Makefile: Likewise for rpc_main. * sysdeps/unix/sysv/linux/Makefile: Likewise for lddlibc4. * timezone/Makefile: Likewise for zic. * stdio-common/perror.c: Avoid multiple calls to fileno_unlocked.
