NAME
idna_to_unicode_44i - API function
SYNOPSIS
#include <idna.h>
int idna_to_unicode_44i(const uint32_t * in, size_t inlen, uint32_t *
out, size_t * outlen, int flags);
ARGUMENTS
const uint32_t * in
input array with unicode code points.
size_t inlen
length of input array with unicode code points.
uint32_t * out
output array with unicode code points.
size_t * outlen
on input, maximum size of output array with unicode code
points, on exit, actual size of output array with unicode
code points.
int flags an Idna_flags value, e.g., IDNA_ALLOW_UNASSIGNED or
IDNA_USE_STD3_ASCII_RULES.
DESCRIPTION
The ToUnicode operation takes a sequence of Unicode code points that
make up one domain label and returns a sequence of Unicode code points.
If the input sequence is a label in ACE form, then the result is an
equivalent internationalized label that is not in ACE form, otherwise
the original sequence is returned unaltered.
ToUnicode never fails. If any step fails, then the original input
sequence is returned immediately in that step.
The Punycode decoder can never output more code points than it inputs,
but Nameprep can, and therefore ToUnicode can. Note that the number of
octets needed to represent a sequence of code points depends on the
particular character encoding used.
The inputs to ToUnicode are a sequence of code points, the AllowUnas-
signed flag, and the UseSTD3ASCIIRules flag. The output of ToUnicode is
always a sequence of Unicode code points.
Return value: Returns Idna_rc error condition, but it must only be used
for debugging purposes. The output buffer is always guaranteed to con-
tain the correct data according to the specification (sans malloc
induced errors). NB! This means that you normally ignore the return
code from this function, as checking it means breaking the standard.
