punycode_decode
#include <punycode.h>
int punycode_decode(size_t input_length, const char [] input, size_t * output_length, punycode_uint [] output, unsigned char [] case_flags);
size_t input_length
The number of ASCII code points in the input array.
const char [] input
An array of ASCII code points (0..7F).
size_t * output_length
The caller passes in the maximum number of code points that it can receive into the output array (which is also the maximum number of flags that it can receive into the
case_flags
array, if case_flags is not a NULL
pointer). On successful return it will contain the number of
code points actually output (which is also the number of
flags actually output, if case_flags is not a null pointer).
The decoder will never need to output more code points than
the number of ASCII code points in the input, because of the
way the encoding is defined. The number of code points
output cannot exceed the maximum possible value of a
punycode_uint, even if the supplied
output_length is greater than that.
punycode_uint [] output
An array of code points like the input argument of
punycode_encode()
(see above).
unsigned char [] case_flags
A NULL
pointer (if the flags are not needed by the caller) or an
array of boolean values parallel to the output array.
Nonzero (true, flagged) suggests that the corresponding
Unicode character be forced to uppercase by the caller (if
possible), and zero (false, unflagged) suggests that it be
forced to lowercase (if possible). ASCII code points (0..7F)
are output already in the proper case, but their flags will
be set appropriately so that applying the flags would be
harmless.
Converts Punycode to a sequence of code points (presumed to be Unicode code points).
The return value can be any of the punycode_status values defined above. If not punycode_success , then
output_length,
output, and case_flags might contain garbage.
