stringprep_4i(3) libidn stringprep_4i(3)
NAME
stringprep_4i - API function
SYNOPSIS
#include <stringprep.h>
int stringprep_4i(uint32_t * ucs4, size_t * len, size_t maxucs4len, Stringprep_pro-
file_flags flags, const Stringprep_profile * profile);
ARGUMENTS
uint32_t * ucs4
input/output array with string to prepare.
size_t * len
on input, length of input array with Unicode code points, on exit, length of
output array with Unicode code points.
size_t maxucs4len
maximum length of input/output array.
Stringprep_profile_flags flags
a Stringprep_profile_flags value, or 0.
const Stringprep_profile * profile
pointer to Stringprep_profile to use.
DESCRIPTION
Prepare the input UCS-4 string according to the stringprep profile, and write back the
result to the input string.
The input is not required to be zero terminated (ucs4[len] = 0). The output will not be
zero terminated unless ucs4[len] = 0. Instead, see stringprep_4zi() if your input is zero
terminated or if you want the output to be.
Since the stringprep operation can expand the string, maxucs4len indicate how large the
buffer holding the string is. This function will not read or write to code points outside
that size.
The flags are one of Stringprep_profile_flags values, or 0.
The profile contain the Stringprep_profile instructions to perform. Your application can
define new profiles, possibly re-using the generic stringprep tables that always will be
part of the library, or use one of the currently supported profiles.
RETURN VALUE
Returns STRINGPREP_OK iff successful, or an Stringprep_rc error code.
