makotoshimazu / arenaoverflow.c
Created January 7, 2014 06:15
arenaが思ったとおりに動作しているか確認するためのコード。 2013/12/27時点でcloneしたmrubyでは正常動作しなかったが、#1637のプルリクで1/3に直っている。 この例だとarenaに保護されているようだが、いつ放置されるのかよくわかっていない。

makotoshimazu / hello_syslog.c
Created May 12, 2014 02:39
syslog関数を利用してsyslogにログを吐いてみるテスト。　userのfacilityのログが出るように、(ubuntu14.04では)/etc/rsyslog.d/50-default.confを編集する必要がある。
#include <stdio.h>
#include <syslog.h>
int main(void)
{
printf("Hello World!\n");
openlog("testmsg", LOG_CONS|LOG_PID, LOG_USER);
syslog(LOG_WARNING, "Hello World!\n");
closelog();
printf("syslog is closed\n");
