| My comment: |
|
The mailslot exists until one of the following conditions is true:
The last (possibly inherited or duplicated) handle to it is closed using the CloseHandle function.
The process owning the last (possibly inherited or duplicated) handle exits.
The system uses the second method to destroy mailslots.
