UUID_UNPARSE(3)             Programmers Manual            UUID_UNPARSE(3)

NAME         top

       uuid_unparse - convert a UUID from binary representation to a
       string

SYNOPSIS         top

       #include <uuid.h>

       void uuid_unparse(const uuid_t uu, char *out);
       void uuid_unparse_upper(const uuid_t uu, char *out);
       void uuid_unparse_lower(const uuid_t uu, char *out);

DESCRIPTION         top

       The uuid_unparse() function converts the supplied UUID uu from the
       binary representation into a 36-byte string (plus trailing '\0')
       of the form 1b4e28ba-2fa1-11d2-883f-0016d3cca427 and stores this
       value in the character string pointed to by out. The case of the
       hex digits returned by uuid_unparse() may be upper or lower case,
       and is dependent on the system-dependent local default.

       If the case of the hex digits is important then the functions
       uuid_unparse_upper() and uuid_unparse_lower() may be used.

CONFORMING TO         top

       This library unparses UUIDs compatible with OSF DCE 1.1.
