Declare Function RasEnumConnections Lib "rasapi32.dll" Alias "RasEnumConnectionsA" (lpRasConn As Any, lpcb As Long, lpcConnections As Long) As Long

Operating Systems Supported
Requires Windows NT 3.1 or later; Requires Windows 95 or later

Library
Rasapi32

Parameter Information
- lprasconn
Points to a buffer that receives an array of RASCONN structures, one for each RAS connection. Before calling the function, an application must set the dwSize member of the first RASCONN structure in the buffer to sizeof(RASCONN) in order to identify the version of the structure being passed.

- lpcb
Points to a variable that contains the size, in bytes, of the buffer specified by lprasconn. On return, the function sets this variable to the number of bytes required to enumerate the RAS connections.

- lpcConnections
Points to a variable that the function sets to the number of RASCONN structures written to the buffer specified by lprasconn.

Return Values
If the function succeeds, the return value is zero.

If the function fails, the return value is a nonzero error value listed in the RAS header file or one of ERROR_BUFFER_TOO_SMALL or ERROR_NOT_ENOUGH_MEMORY.
