size_t input_length
The number of code points in the _i_n_p_u_t array and the num-
ber of flags in the _c_a_s_e___f_l_a_g_s array.
const punycode_uint [] input
An array of code points. They are presumed to be Unicode
code points, but that is not strictly REQUIRED. The array
contains code points, not code units. UTF-16 uses code
units D800 through DFFF to refer to code points
10000..10FFFF. The code points D800..DFFF do not occur in
any valid Unicode string. The code points that can occur
in Unicode strings (0..D7FF and E000..10FFFF) are also
called Unicode scalar values.
const unsigned char [] case_flags
A NNUULLLL pointer or an array of boolean values parallel to
the _i_n_p_u_t array. Nonzero (true, flagged) suggests that
the corresponding Unicode character be forced to uppercase
after being decoded (if possible), and zero (false,
unflagged) suggests that it be forced to lowercase (if pos-
sible). ASCII code points (0..7F) are encoded literally,
except that ASCII letters are forced to uppercase or lower-
case according to the corresponding case flags. If
_c_a_s_e___f_l_a_g_s is a NNUULLLL pointer then ASCII letters are left as
they are, and other code points are treated as unflagged.
size_t * output_length
The caller passes in the maximum number of ASCII code
points that it can receive. On successful return it will
contain the number of ASCII code points actually output.
char [] output
An array of ASCII code points. It is *not* null-termi-
nated; it will contain zeros if and only if the _i_n_p_u_t con-
tains zeros. (Of course the caller can leave room for a
terminator and add one if needed.)
DDEESSCCRRIIPPTTIIOONN
Converts a sequence of code points (presumed to be Unicode code points)
to Punycode.
Return value: The return value can be any of the PPuunnyyccooddee__ssttaattuuss values
defined above except PPUUNNYYCCOODDEE__BBAADD__IINNPPUUTT. If not PPUUNNYYCCOODDEE__SSUUCCCCEESSSS, then
_o_u_t_p_u_t___s_i_z_e and _o_u_t_p_u_t might contain garbage.
