This embedded program is untested as I no longer have a working Windows machine but should work when run with administrative privileges - what can possibly go wrong?
<lang ecmascript>/* write_to_windows_event_log.wren */
 
class Windows {
foreign static eventCreate(args)
}
 
var args = [
"/T", "INFORMATION", "/ID", "123", "/L", "APPLICATION",
"/SO", "Wren", "/D", "\"Rosetta Code Example\""
].join(" ")
 
Windows.eventCreate(args)</lang>

Now embed this script in the following C program, compile and run it.
<lang c>#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "wren.h"

char command[strlen(args) + 13];
strcpy(command, "EventCreate ");
strcat(command, args);
system(command);
}
 
WrenForeignMethodFn bindForeignMethod(
WrenVM* vm,
const char* module,
const char* className,
bool isStatic,
const char* signature) {

}
}
return NULL;
}
