PvGetDbName()

Gets the name of a database on a connected server using a sequence number. You can obtain the number of database names by calling the PvGetDbNamesData() function. The sequence number is 1 based.

BTI_API PvGetDbName(

BTI_LONG hConnection,

BTI_ULONG sequence,

BTI_ULONG_PTR pBufSize,

BTI_CHAR_PTR dbName);


In	hConnection	Connection handle that identifies the server. Connection handles are obtained with the PvConnectServer() function.
In	sequence	The sequence number (1 based) of the database name. Must be within a valid range with upper limit defined by PvGetDbNamesData().
In/Out	pBufSize	Address of an unsigned long containing size of buffer allocated to receive the database name. Receives actual size of chars copied. The size should include the null terminator.
Out	dbName	String value returned.


P_OK	The operation was successful.
P_E_INVALID_HANDLE	Invalid connection handle.
P_E_DATA_UNAVAILABLE	Data related to database names not available.
P_E_NULL_PTR	Call with NULL pointer
P_E_BUFFER_TOO_SMALL	Allocated buffer is too small for the string.
P_E_INVALID_SEQUENCE	Sequence number is not valid.
P_E_FAIL	Failed for other reasons.

BTI_ULONG count = 0;

BTI_CHAR dbName[BDB_SIZE_DBNAME+1];

BTI_SINT status = PvGetDbNamesData(connection, &count);

for (i=1; i<= count; i++)

BTI_ULONG dbNameSize = sizeof(dbName);

status = PvGetDbName(connection, i, &dbNameSize, dbName);

status = PvFreeDbNamesData(connection);

The following preconditions must be met:

•

DTI session started by calling PvStart().

•

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.

•

Database names data retrieved by calling PvGetDbNamesData()

•

Caller has a valid database name sequence number.
