Init the UUID from the specified string which must be at least 38 characters long and must be of the form {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}.

| void UUID::fillString | ( | char * | guid_str, |
| bool | zero_terminate = true |
||
| ) | const |
Fills a buffer with an ascii representation of the UUID of type {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}.
| guid_str | must point to a buffer of at least 38 byes; if zero_terminate is true (default) then it must be at least 39 bytes large. |
| zero_terminate | if true the function inserts a trailing 0 at the end of the string, in this case guid_str must point to a buffer 39 bytes large at least. |
