|
|
* 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.
