* libc/include/stdio.h: Add new iprintf and iscanf variants. Also do some reordering. * libc/machine/powerpc/vfscanf.c: Remove __sccl function. * libc/stdio/Makefile.am: Add support for new iprintf and iscanf family functions. * libc/stdio/Makefile.in: Regenerated. * libc/stdio/fiprintf.c: Remove doc to siprintf.c. * libc/stdio/iprintf.c: Ditto. * libc/stdio/local.h (__svfiscanf_r): New prototype. * libc/stdio/siprintf.c: Add docs for various iprintf family functions. * libc/stdio/sniprintf.c: Move docs to siprintf.c. * libc/stdio/stdio.tex: Add new functions. * libc/stdio/vfscanf.c: Split out __sccl function to separate file and add special name defines so this file can be used to build vfiscanf.o. * libc/stdio/asiprintf.c: New file. * libc/stdio/fiscanf.c: Ditto. * libc/stdio/iscanf.c: Ditto. * libc/stdio/sccl.c: Ditto. * libc/stdio/siscanf.c: Ditto. * libc/stdio/vasiprintf.c: Ditto. * libc/stdio/viprintf.c: Ditto. * libc/stdio/viscanf.c: Ditto. * libc/stdio/vsiprintf.c: Ditto. * libc/stdio/vsiscanf.c: Ditto. * libc/stdio/vsniprintf.c: Ditto.

+FUNCTION
+<<vsniprintf>>---write formatted output (integer only)
+
+INDEX
+ vsniprintf
+
+ANSI_SYNOPSIS
+ #include <stdio.h>
+
+ int vsniprintf(char *<[str]>, size_t <[size]>, const char *<[fmt]>, va_list <[list]>);
+
+TRAD_SYNOPSIS
+ #include <stdio.h>
+
+ int vsnprintf(<[str]>, <[size]>, <[fmt]>, <[list]>)
+ char *<[str]>;
+ size_t <[size]>;
+ char *<[fmt]>;
+ va_list <[list]>;
+
+DESCRIPTION
+<<vsniprintf>> is a restricted version of <<vsnprintf>>: it has the same
+arguments and behavior, save that it cannot perform any floating-point
+formatting: the <<f>>, <<g>>, <<G>>, <<e>>, and <<F>> type specifiers
+are not recognized.
+
+RETURNS
+ <<vsniprintf>> returns the number of bytes in the output string,
+ save that the concluding <<NULL>> is not counted.
+ <<vsniprintf>> returns when the end of the format string is
+ encountered.
+
+PORTABILITY
+<<vsniprintf>> is not required by ANSI C.
+
+Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
+<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
