** The "printf" code that follows dates from the 1980's. It is in
3
** the public domain. The original comments are included here for
4
** completeness. They are very out-of-date but might be useful as
5
** an historical reference. Most of the "enhancements" have been backed
6
** out so that the functionality is now the same as standard printf().
8
**************************************************************************
10
** The following modules is an enhanced replacement for the "printf" subroutines
11
** found in the standard C library. The following enhancements are
14
** + Additional functions. The standard set of "printf" functions
15
** includes printf, fprintf, sprintf, vprintf, vfprintf, and
16
** vsprintf. This module adds the following:
18
** * snprintf -- Works like sprintf, but has an extra argument
19
** which is the size of the buffer written to.
21
** * mprintf -- Similar to sprintf. Writes output to memory
22
** obtained from malloc.
24
** * xprintf -- Calls a function to dispose of output.
26
** * nprintf -- No output, but returns the number of characters
27
** that would have been output by printf.
29
** * A v- version (ex: vsnprintf) of every function is also
32
** + A few extensions to the formatting notation are supported:
34
** * The "=" flag (similar to "-") causes the output to be
35
** be centered in the appropriately sized field.
37
** * The %b field outputs an integer in binary notation.
39
** * The %c field now accepts a precision. The character output
40
** is repeated by the number of times the precision specifies.
42
** * The %' field works like %c, but takes as its character the
43
** next character of the format string, instead of the next
44
** argument. For example, printf("%.78'-") prints 78 minus
45
** signs, the same as printf("%.78c",'-').
47
** + When compiled using GCC on a SPARC, this version of printf is
48
** faster than the library printf for SUN OS 4.1.
50
** + All functions are fully reentrant.
