UUID_PARSE(3) Programmers Manual UUID_PARSE(3) NAME uuid_parse - convert an input UUID string into binary representation SYNOPSIS #include <uuid.h> int uuid_parse(const char *in, uuid_t uu); int uuid_parse_range(const char *in_start, const char *in_end, uuid_t uu); DESCRIPTION The uuid_parse() function converts the UUID string given by in into the bi- nary representation. The input UUID is a string of the form 1b4e28ba-2fa1-11d2-883f-b9a761bde3fb (in printf(3) format "%08x-%04x-%04x-%04x-%012x", 36 bytes plus the trailing '\0'). The uuid_parse_range(3) function works like uuid_parse() but parses only range in string specified by in_start and in_end pointers. RETURN VALUE Upon successfully parsing the input string, 0 is returned, and the UUID is stored in the location pointed to by uu, otherwise -1 is returned. CONFORMING TO This library parses UUIDs compatible with OSF DCE 1.1, and hash based UUIDs V3 and V5 compatible with RFC-4122 <https://tools.ietf.org/html/rfc4122>. AUTHORS Theodore Y.
