Get the system error code of the last command.

A system error code or 0 if the last operation of the module was executed sucessfully.

This function reports the current system error code (corresponding to the C-variable errno on Posix and the C-function GetLastError() on Windows): it can be used after getsysstat has returned a non-zero status to get the actual system error (if the failure was actually due to a system error). This code is system dependent but the corresponding error message might be retrieved using getoserrmsg.
