sys.set_ldata()

Purpose:

sys.set_ldata() sends data to an open LData connection.

Usage:

ret = sys.set_ldata(<ldname>, <flags>);

Arguments:

<ldname> - an alpha var that was used in a previous call to sys.open_ldata()

<flags> - can be one of:

• LD_DEFAULT - Using LD_DEFAULT, sys.set_ldata() will not return until the send data has been acknowledged or an error has been returned from the external process.
• LD_NOWAIT - Send the data but don't wait for acknowledgement before returning. Using LD_NOWAIT is faster but your application will not know for sure if the data was accepted by the external process.

Returns:

-1 = Failure and sys.errno will be set. Probably no open LData connection with name <ldname>.

0 - Success

Where Used:

sys.set_ldata() can be called from anywhere.

Example:

Description:

Use sys.set_ldata() to send data to a non onetime LData connection. The data sent will be copied from the field specified int the sys.open_ldata() call.
