tld_check_4(3) libidn tld_check_4(3)
NAME
tld_check_4 - verify that characters are permitted
SYNOPSIS
#include <tld.h>
int tld_check_4(const uint32_t * in, size_t inlen, size_t * errpos, const Tld_table **
overrides);
ARGUMENTS
const uint32_t * in
Array of unicode code points to process. Does not need to be zero terminated.
size_t inlen
Number of unicode code points.
size_t * errpos
Position of offending character is returned here.
const Tld_table ** overrides
A Tld_table array of additional domain restriction structures that complement
and supersede the built-in information.
DESCRIPTION
Test each of the code points in in for whether or not they are allowed by the information
in overrides or by the built-in TLD restriction data. When data for the same TLD is avail-
able both internally and in overrides, the information in overrides takes precedence. If
several entries for a specific TLD are found, the first one is used. If overrides is
NULL, only the built-in information is used. The position of the first offending charac-
ter is returned in errpos.
RETURN VALUE
Returns the Tld_rc value TLD_SUCCESS if all code points are valid or when tld is null,
TLD_INVALID if a character is not allowed, or additional error codes on general failure
conditions.
