Introduction
...
This explanation assumes that the i-PRO camera application development environment has been completed.
If you are not ready to build the development environment, please refer to here to complete it.
Also, in this tutorial, the SDK installation directory is described as を${SDK_DIR}.
Operation overview
...
freestyle_app_with_keepalive and keepalive_sample_app are is a sample application that creates a subthread with life and death monitoring from the main thread.
External libraries required for operation
...
No special mention.
Directory path of the sample app
...
The C/C++ source code is stored below.
${SDK_DIR}/src/adamapp/freestyle_app_with_keepalive
The No Python source code is stored below.
${SDK_DIR}/src/adamapp-py/keepalive_sample_app
How to build the sample app (C/C++)
...
Load the build environment settings file in the SDK installation directory.

How to use the sample app(C/C++)
...
A debug log is output that notifies KeepAlive for life-and-death monitoring.
...
How to use the sample app(Python)
Check the Python debug log to make sure it's alive and well. Press the red frame button below to get syslog.tgz.
...
Unzip syslog.tgz, then unzip mnt/log/pflog.tgz.
Debug logs are output to pf_<install ID>_<processId>.log in log/adam. You can check the debug log that notified KeepAlive for life and death monitoring.
