| 18 * A note to trio contributors: | |
| 19 * | |
| 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. | |
| 24 * | |
| 25 ************************************************************************/ | |
| 26 | |
| 27 /* | |
| 28 * TODO: | |
| 29 * - Scan is probably too permissive about its modifiers. | |
| 30 * - C escapes in %#[] ? | |
| 31 * - Multibyte characters (done for format parsing, except scan groups) | |
| 32 * - Complex numbers? (C99 _Complex) | |
| 33 * - Boolean values? (C99 _Bool) | |
| 34 * - C99 NaN(n-char-sequence) missing. The n-char-sequence can be used | |
| 35 * to print the mantissa, e.g. NaN(0xc000000000000000) | |
| 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'. | |
| 41 * - Scanning of collating symbols. | |
