The NetUseGetInfo API retrieves information about a connection to a shared resource.
Restrictions
This API can be called from DLS and OS/2 workstations. Administrator authority is required to call this API remotely. However, no access authority is required for local execution.
#include <netcons.h> #include <use.h> NetUseGetInfo(pszServername, netname, sLevel, buf, usBuflen, pusBytesAvail); /* 16 bit */ Net32UseGetInfo(pszServername, netname, ulLevel, buf, ulBuflen, pulBytesAvail); /* 32 bit */Parameters
See Common Parameter Definitions for descriptions of parameters not defined here.

Other codes could be returned from the following functions:
If you call this API with the buffer length parameter equal to zero, the API returns a value for total bytes available. This technique is useful if you do not know the exact buffer size required.
The NetUseGetInfo function returns the ui1_password component as a null pointer, so users or applications cannot determine the password of another user or application.
