BTI_SINT PvGetDbDataPath( 
	BTI_LONG           hConnection, 
	BTI_CHAR_PTR       dbName, 
	BTI_ULONG_PTR      pBufSize, 
	BTI_CHAR_PTR       dataPath);

Arguments


In	hConnection	Connection handle that identifies the server. Connection handles are obtained with the PvConnectServer() function.
In	dbName	Name of the database. A list of all database names for a particular server is obtained with the PvGetDbNamesData() function. A single database name from the resulting list can be obtained with the PvGetDbName() function.
In/Out	pBufSize	Address of an unsigned long containing size of the buffer. Receives actual size of the path returned.
Out	dataPath	Contains the data path if successful, or empty string otherwise.

Return Values


P_OK	The operation was successful.
P_E_INVALID_HANDLE	Invalid connection handle.
P_E_NULL_PTR	Call with NULL pointer
P_E_BUFFER_TOO_SMALL	The buffer is too small for the string. In this case, the required buffer size is returned in pBufSize.
P_E_NOT_EXIST	Named database does not exist.
P_E_FAIL	Failed for other reasons.

The following precondition must be met:

Connection established by PvConnectServer() or if you are performing the operation on a local machine, P_LOCAL_DB_CONNECTION may be used as the connection handle.
