Synopsis

OpenLog

Without the call to closelog, future invocations of syslog by the program using the shared library may crash, if the library gets unloaded and the memory containing the string "mylibrary" becomes unmapped. This is a limitation of the BSD syslog interface. openlog may or may not open the /dev/log socket, depending on option.If it does, it tries to open it and connect it as a stream …

OpenLog_Benchmarking-- This example is used to test OpenLog. This sends very large amounts of data at 115200bps over multiple files. OpenLog_CommandTest-- This example shows how to create and append a file via command line control through the Arduino. OpenLog_ReadExample-- This example runs through how to control the OpenLog via command line.

openlog opens or reopens a connection to Syslog in preparation for submitting messages. ident is an arbitrary identification string which future syslog invocations will prefix to each message. This is intended to identify the source of the message, and people conventionally set it to the name of the program that will submit the messages.
