As both C and C++ standards require applications running under an OS to
return 'int', adapt that for Zephyr to align with those standard. This also
eliminates errors when building with clang when not using -ffreestanding,
and reduces the need for compiler flags to silence warnings for both clang
and gcc.
Most of these changes were automated using coccinelle with the following
script:
@@
@@
- void
+ int
main(...) {
...
- return;
+ return 0;
...
}
Approximately 40 files had to be edited by hand as coccinelle was unable to
fix them.

.. _die_temp_polling:
CPU Die Temperature polling
###########################
Overview
********
This sample periodically reads temperature from the CPU Die
temperature sensor and display the results.
Building and Running
********************
To run this sample, enable the sensor node that supports ``SENSOR_CHAN_DIE_TEMP``
and create an alias named ``die-temp0`` to link to the node.
The tail ``0`` is the sensor number. This sample support up to 15 sensors.
