event_id is defined in the mc.h
Look at the mc.h :
#define CATEGORY_ERROR 0x00000001L
#define CATEGORY_WARNING 0x00000002L
#define FOO_ERROR 0xC0000003L

You must call with event_id value 0xC0000003 instead of 0x3.
But it raises error
test.rb:7:in `write': bignum too big to convert into `long' (RangeError)
It is another problem.

And tail method raises insufficient resource error after reading six
event log messages.
