uuid_unparse - convert a UUID from binary representation to a string

#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);

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.

This library unparses UUIDs compatible with OSF DCE 1.1.
