Routine Description:
|
|
|
|
Forms a name that is very probably unique in the system, based on
|
|
the current process and thread id and a sequence provided by the
|
|
caller.
|
|
|
|
Arguments:
|
|
|
|
Name - Supplies a unicode string where the name will be put.
|
|
This string must contain a valid buffer of size
|
|
MAX_PATH * sizeof(WCHAR)
|
|
|
|
Sequence - Supplies a sequence number that will be appended to
|
|
the name. If a name happens not to be unique, the
|
|
caller can try again with other sequence numbers.
|
|
|
|
Return Value:
|
|
|
|
BOOL - Returns TRUE if a name was obtained.
