18 * A note to trio contributors:
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.
25 ************************************************************************/
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
35 * - Should we support the GNU %a alloc modifier? GNU has an ugly hack
36 * for %a, because C99 used %a for other purposes. If specified as
37 * %as or %a[ it is interpreted as the alloc modifier, otherwise as
38 * the C99 hex-float. This means that you cannot scan %as as a hex-float
39 * immediately followed by an 's'.
40 * - Scanning of collating symbols.
