| 21 |
|
|
* Manuel Novoa III Dec 2000
|
| 22 |
|
|
*
|
| 23 |
|
|
* The previous vfnprintf routine was almost completely rewritten with the
|
| 24 |
|
|
* goal of fixing some shortcomings and reducing object size.
|
| 25 |
|
|
*
|
| 26 |
|
|
* The summary of changes:
|
| 27 |
|
|
*
|
| 28 |
|
|
* Converted print conversion specification parsing from one big switch
|
| 29 |
|
|
* to a method using string tables. This new method verifies that the
|
| 30 |
|
|
* conversion flags, field width, precision, qualifier, and specifier
|
| 31 |
|
|
* appear in the correct order. Many questionable specifications were
|
| 32 |
|
|
* accepted by the previous code. This new method also resulted in a
|
| 33 |
|
|
* substantial reduction in object size of about 330 bytes (20%) from
|
| 34 |
|
|
* the old version (1627 bytes) on i386, even with the following
|
| 35 |
|
|
* improvements.
|
| 36 |
|
|
*
|
| 37 |
|
|
* Implemented %n specifier as required by the standards.
|
| 38 |
|
|
* Implemented proper handling of precision for int types.
|
| 39 |
|
|
* Implemented # for hex and pointer, fixed error for octal rep of 0.
|
| 40 |
|
|
* Implemented return of -1 on stream error.
|
| 41 |
|
|
*
|
| 42 |
|
|
* Added optional support for the GNU extension %m which prints the string
|
| 43 |
|
|
* corresponding the errno.
|
| 44 |
|
|
*
|
| 45 |
|
|
* Added optional support for long long ints and unsigned long long ints
|
| 46 |
|
|
* using the conversion qualifiers "ll", "L", or "q" (like glibc).
|
| 47 |
|
|
*
|
| 48 |
|
|
* Added optional support for doubles in a very limited form. None of
|
| 49 |
|
|
* the formating options are obeyed. The string returned by __dtostr
|
| 50 |
|
|
* is printed directly.
|
| 51 |
|
|
*
|
| 52 |
|
|
* Converted to use my (un)signed long (long) to string routines, which are
|
| 53 |
|
|
* smaller than the previous functions and don't require static buffers.
|
| 54 |
|
|
*
|
| 55 |
|
|
* Other Modifications:
|
| 56 |
|
|
* Modified sprintf, snprintf, vsprintf, vsnprintf to share on fake-file.

|
|
* Manuel Novoa III Jan 2001
|
| 61 |
|
|
*
|
| 62 |
|
|
* Removed fake file from *s*printf functions because of possible problems
|
| 63 |
|
|
* if called recursively. Instead, have sprintf, snprintf, and vsprintf
|
| 64 |
|
|
* call vsnprintf which allocates a fake file on the stack.
|
| 65 |
|
|
* Removed WANT_FPUTC option. Always use standard putc macro to avoid
|
| 66 |
|
|
* problems with the fake file used by the *s*printf functions.
|
| 67 |
|
|
* Fixed bug parsing flags -- did not restart scan.
|
| 68 |
|
|
* Added function asprintf.
|
| 69 |
|
|
* Fixed 0-pad prefixing bug.
|
| 70 |
|
|
* Converted sizeof(int) == sizeof(long) tests to compile time vs run time.
|
| 71 |
|
|
* This saves 112 bytes of code on i386.
|
| 72 |
|
|
* Fixed precision bug -- when negative set to default.
|
| 73 |
|
|
* Added function fnprintf to support __dtostr.
|
| 74 |
|
|
* Added floating point support for doubles. Yeah!
|
| 75 |
|
|
*
|
| 76 |
|
|
*
|
| 77 |
|
|
* May 2001 Fixes from Johan Adolfsson (johan.adolfsson@axis.com)
|
| 78 |
|
|
* 1) printf("%c",0) returned 0 instead of 1.
|
| 79 |
|
|
* 2) unrolled loop in asprintf to reduce size and remove compile warning.
|
| 80 |
|
|
*
|
| 81 |
|
|
*
|
| 82 |
|
|
* June 2001
|
| 83 |
|
|
* 1) fix %p so that "0x" is prepended to outputed hex val
|
| 84 |
|
|
* 2) fix %p so that "(nil)" is output for (void *)0 to match glibc
|
| 85 |
|
|
*
|
| 86 |
|
|
* Sep 5, 2003
|
| 87 |
|
|
* Convert to new floating point conversion routine.
|
| 88 |
|
|
* Fix qualifier handling on integer and %n conversions.
|
| 89 |
|
|
* Add support for vsnprintf when in non-buffered/no-wchar configuration.
