    UNIQUEID_ERROR

    MU_DEFINE_ENUM(UNIQUEID_RESULT, UNIQUEID_RESULT_VALUES)

    extern UNIQUEID_RESULT UniqueId_Generate(char* uid, size_t bufferSize);
```
###  UniqueId_Generate
```C
extern UNIQUEID_RESULT UniqueId_Generate(char* uid, size_t len);
```
**SRS_UNIQUEID_07_001: [** UniqueId_Generate shall create a unique Id 36 character long string. **]**

**SRS_UNIQUEID_07_002: [** If uid is NULL then UniqueId_Generate shall return UNIQUEID_INVALID_ARG **]**

**SRS_UNIQUEID_07_003: [** If len is less then 37 then UniqueId_Generate shall return UNIQUEID_INVALID_ARG **]**

**SRS_UNIQUEID_07_004: [** If there is a failure for any reason the UniqueId_Generate shall return UNIQUEID_ERROR **]**
