punycode_decode(3) -- Linux man page
- 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
- unsigned char  case_flags
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.
DESCRIPTIONConverts 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
