idn_checkname(3) Library Functions Manual idn_checkname(3) NAME idn_checkname - validate an internationalized domain name SYNOPSIS #include <idn/api.h> idn_result_t idn_checkname(idn_action_t actions, const char *from); DESCRIPTION The function idn_checkname() internally creates a copy of name, encodes it with idn_encodename() and returns its error code. In addition with action macros for idn_encodename() (e.g. IDN_UNICODECONV), the following macros are available for idn_checkname(). IDN_CHECK_REGIST Encode a domain name with IDNA2008 registration protocol to val- idate a domain name. Currently, its value is the same as IDN_ENCODE_REGIST. IDN_CHECK_LOOKUP Encode a domain name with IDNA2008 lookup protocol to validate a domain name. Currently, its value is the same as IDN_EN- CODE_LOOKUP. EXAMPLES The program below shows an example of idn_checkname(). idn_result_t r; ... r = idn_checkname(IDN_CHECK_REGIST, name); if (r == idn_success) fprintf(stderr, "'%s' is valid\n", name); else { fprintf(stderr, "'%s' is not valid: %s\n", name, idn_result_tostring(r)); } ...
