-/* Author's Note
- * This buf.c is base on C99, that is, if buffer size is not enough,
- * the return value of vsnprintf(3) is a number tell how many character should
- * be output.  vsnprintf in glibc 2.1 conforms to C99 , but glibc 2.0 doesn't.
- * see manpage of vsnprintf(3) on you platform for more detail.
-
- * So, what should you do if you want to using zlog on the platform that doesn't
- * conform C99? My Answer is, crack zlog with a portable C99-vsnprintf, like this
- * http://sourceforge.net/projects/ctrio/
- * http://www.jhweiss.de/software/snprintf.html
- * If you can see this note, you can fix it yourself? Aren't you? ^_^
-
- * Oh, I put the snprintf in C99 standard here,
- * vsnprintf is the same on return value.
-
-       7.19.6.5  The snprintf function
-
-       Synopsis
-
-       [#1]
-
-               #include <stdio.h>
-               int snprintf(char * restrict s, size_t n,
-                       const char * restrict format, ...);
-
-       Description
-
-       [#2]  The snprintf function is equivalent to fprintf, except
-       that the output is  written  into  an  array  (specified  by
-       argument  s) rather than to a stream.  If n is zero, nothing
-       is written, and s may be a null pointer.  Otherwise,  output
-       characters  beyond the n-1st are discarded rather than being
-       written to the array, and a null character is written at the
-       end  of  the characters actually written into the array.  If
-       copying  takes  place  between  objects  that  overlap,  the
-       behavior is undefined.
-
-       Returns
-
-       [#3]  The snprintf function returns the number of characters
-       that would have been written had n been sufficiently  large,
-       not  counting  the terminating null character, or a negative
-       value if  an  encoding  error  occurred.   Thus,  the  null-
-       terminated output has been completely written if and only if
-       the returned value is nonnegative and less than n.
