| * A note to trio contributors: |
| * |
| * Avoid heap allocation at all costs to ensure that the trio functions |
| * are async-safe. The exceptions are the printf/fprintf functions, which |
| * uses fputc, and the asprintf functions and the <alloc> modifier, which |
| * by design are required to allocate form the heap. |
| * |
| ************************************************************************/ |
| |
| /* |
| * TODO: |
| * - Scan is probably too permissive about its modifiers. |
| * - C escapes in %#[] ? |
| * - Multibyte characters (done for format parsing, except scan groups) |
| * - Complex numbers? (C99 _Complex) |
| * - Boolean values? (C99 _Bool) |
| * - C99 NaN(n-char-sequence) missing. The n-char-sequence can be used |
| * to print the mantissa, e.g. NaN(0xc000000000000000) |
| * - Should we support the GNU %a alloc modifier? GNU has an ugly hack |
| * for %a, because C99 used %a for other purposes. If specified as |
| * %as or %a[ it is interpreted as the alloc modifier, otherwise as |
| * the C99 hex-float. This means that you cannot scan %as as a hex-float |
| * immediately followed by an 's'. |
| * - Scanning of collating symbols. |
