tld_check_4z(3)

tld_check_4z3

Api function

Usage

#include <tld.h>

int tld_check_4z(const uint32_t * in, size_t * errpos, const Tld_table ** overrides);

Arguments

const uint32_t * in

Zero-terminated array of unicode code points to process.

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.

Overview

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 available 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 character 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.
