Daniel Veillard | 92ad210 | 2001-03-27 12:47:33 +0000 | [diff] [blame] | 20 | * Avoid heap allocation at all costs to ensure that the trio functions |
| 21 | * are async-safe. The exceptions are the printf/fprintf functions, which |
| 22 | * uses fputc, and the asprintf functions and the <alloc> modifier, which |
| 23 | * by design are required to allocate form the heap. |

Daniel Veillard | 92ad210 | 2001-03-27 12:47:33 +0000 | [diff] [blame] | 29 | * - Scan is probably too permissive about its modifiers. |
Daniel Veillard | 92ad210 | 2001-03-27 12:47:33 +0000 | [diff] [blame] | 30 | * - C escapes in %#[] ? |
Bjorn Reese | 70a9da5 | 2001-04-21 16:57:29 +0000 | [diff] [blame] | 31 | * - C99 support has not been properly tested. |
Daniel Veillard | 92ad210 | 2001-03-27 12:47:33 +0000 | [diff] [blame] | 32 | * - Multibyte characters (done for format parsing, except scan groups) |
Daniel Veillard | 92ad210 | 2001-03-27 12:47:33 +0000 | [diff] [blame] | 33 | * - Complex numbers? (C99 _Complex) |
| 34 | * - Boolean values? (C99 _Bool) |
| 35 | * - C99 NaN(n-char-sequence) missing |
| 36 | * - Should we support the GNU %a alloc modifier? GNU has an ugly hack |
| 37 | * for %a, because C99 used %a for other purposes. If specified as |
| 38 | * %as or %a[ it is interpreted as the alloc modifier, otherwise as |
| 39 | * the C99 hex-float. This means that you cannot scan %as as a hex-float |
| 40 | * immediately followed by an 's'. |
