Create a new GUID
Source position: sysutilh.inc line 181
function CreateGUID( |
out GUID: TGUID |
):Integer; |
CreateGUID can be called to create a new GUID (Globally Unique Identifier) value. The function returns the new GUID value in GUID and returns zero in case the GUID was created succesfully. If no GUID was created, a nonzero error code is returned.
The default mechanism for creating a new GUID is system dependent. If operating system support is available, it is used. If none is available, a default implementation using random numbers is used.
The OnCreateGUID callback can be set to hook a custom mechanism behind the CreateGUID function. This can be used to lt the GUID be created by an external GUID creation library.
On error, a nonzero return value is returned.
