I am calling NetUseAdd to connect to a remote share on local machine (i.e. UncServerName is null). I am passing level 2 info (i.e. USE_INFO_2) with username and password to connect. Later when task is done, I am calling NetUseDel to close the connection using USE_LOTS_OF_FORCE to close the connection.
My question is: Why NetUseDel would close the connection even if there are more than one call to NetUseAdd for same share and same credentials? How to control it (possibly using same force flag). Importantly, what if net use command is used to add or delete connection? I see the process (having called any of these functions) wouldn't have any control over it.
My point is there should be security or reference-counting for Add, and only when corresponding Delete calls are there, then only OS should close the connection.
