** Formatted input/output functions.
|
|
**
|
|
** These functions implement most of printf(3)'s features, including:
|
|
** - Signed and unsigned integer formats (%d, %i, %o, %u, %x, %X)
|
|
** - Character, string and pointer formats (%c, %s, %p)
|
|
** - Character count and strerror() shorthand formats (%n, %m)
|
|
** - Format options (0, #, -, (space), length, precision)
|
|
** - Parameter length (hh, h, l, ll, z)
|
|
** - Limiting the size of the output and still returning the whole length
|
|
** - If __printf_enable_fp() from <fxlibc/printf.h> is called: floating-point
|
|
** formats (%e, %E, %f, %F, %g, %G) (disabled by default to save space)
|
|
**
|
|
** They do not support:
|
|
** - Hexadecimal floating-point (%a, %A)
|
|
** - Some size modifiers: long double (L), intmax_t (j), ptrdiff_t (t), and the
|
|
** nonstandard synonyms q (ll) and Z (z)
|
|
** - Dynamic length field (*)
|
|
** - Thousands separators (') and locale-aware digits (I)
|
|
** - Nonstandard synonyms %C (%lc) and %S (%ls)
|
|
**
|
|
** There are extensions, namely to allow for custom conversions to be added.
|
|
** One custom conversion can be enabled with __printf_enable_fixed() from
|
|
** <fxlibc/printf.h>: a decimal fixed-point format %k which is like %d but
|
|
** with a decimal point. See <fxlibc/printf.h> for details.
