Management of Errors Example

When an error occurs, it is desirable to analyze and fix the error. The following error
display and socket closing procedure is useful to detect and display the errors during the
execution of a program. This sequence could be added to each program and called each
time users need to test certain parts of a program.
Display error and close procedure:
Display API name, error code
and ErrorStringGet error
Display Timeout error
