POSIX errors

Debugging

Some locations use POSIX-STYLE error codes, which are positive numbers. The constant names are the same as Linux errno values, but some of the numeric values are different. The constants are defined in newlib which is the standard C/C++ library that Device OS uses.

For example, you might see the following debugging message in code that uses TCPClient, where 113 is ECONNABORTED (connection aborted).
