**************************************************************************
**
** The following modules is an enhanced replacement for the "printf" subroutines
** found in the standard C library. The following enhancements are
** supported:
**
** + Additional functions. The standard set of "printf" functions
** includes printf, fprintf, sprintf, vprintf, vfprintf, and
** vsprintf. This module adds the following:
**
** * snprintf -- Works like sprintf, but has an extra argument
** which is the size of the buffer written to.
**
** * mprintf -- Similar to sprintf. Writes output to memory
** obtained from malloc.
**
** * xprintf -- Calls a function to dispose of output.
**
** * nprintf -- No output, but returns the number of characters
** that would have been output by printf.
**
** * A v- version (ex: vsnprintf) of every function is also
** supplied.
**
** + A few extensions to the formatting notation are supported:
**
** * The "=" flag (similar to "-") causes the output to be
** be centered in the appropriately sized field.
**
** * The %b field outputs an integer in binary notation.
**
** * The %c field now accepts a precision. The character output
** is repeated by the number of times the precision specifies.
**
** * The %' field works like %c, but takes as its character the
** next character of the format string, instead of the next
** argument. For example, printf("%.78'-") prints 78 minus
** signs, the same as printf("%.78c",'-').
**
** + When compiled using GCC on a SPARC, this version of printf is
** faster than the library printf for SUN OS 4.1.
**
** + All functions are fully reentrant.
**
** This file contains code for a set of "printf"-like routines. These
** routines format strings much like the printf() from the standard C
** library, though the implementation here has enhancements to support
** SQLlite.

** 2. A pointer to the list of characters to be output
