Exit Codes

The MicroEJ Application can stop its execution by calling the method System.exit(). To retrieve the appplication exit code (or exit status), use the C function SNI_getExitCode() after the end of SNI_startVM() (see sni.h header file). If the MicroEJ Application ended without calling System.exit() then SNI_getExitCode() returns 0.

The error codes returned by SNI_startVM() are defined in the section Error Codes.
