High Level subroutine
Disconnect from a data source and free associated handles.
call EDSDeInitEnv(HENV_IV )
•HENV_IV An input integer value indicating the environment handle
Description
EDSDeInitEnv calls EDSFreeStmt, EDSDisconnect, EDSFreeConnect, and EDSFreeEnv. This command disconnects all connections and frees all statement handles, connection handles, and the environment handle.
Return Values
EDSDeInitEnv returns EDS_SUCCESS, EDS_SUCCESS_WITH_INFO, EDS_INVALID_HANDLE, or EDS_ERROR.
When EDSDeInitEnv returns EDS_ERROR, you can obtain an associated SQLSTATE value with more specific information by calling EDSError. The following table lists each typical SQLSTATE value and explains each one in the context of the command EDSDeInitEnv.
The following table lists possible SQLSTATE values.

Invalid transaction state |
There was a transaction in process on the connection specified by the argument HDBC_IV. The transaction remains active. |
IM001 |
Driver does not support this function |
The driver associated with the statement handle does not support the function. |
S1000 |
General error |
An error occurred for which there was no specific SQLSTATE and for which no implementation-specific SQLSTATE was defined. The error message returned by EDSError in the argument ERRORTEXT describes the error and its cause. |
