The Valgrind distribution has multiple tools. The most popular is the memory checking tool (called Memcheck) which can detect many common memory errors such as: * touching memory you shouldn t (eg. overrunning heap block boundaries) * using values before they have been initialized * incorrect freeing of memory, such as double-freeing heap blocks * memory leaks. -The Valgrind distribution has to multiple ols.

Linux是一类Unix计算机操作系统的统称。Linux操作系统的内核的名字也是“Linux”。Linux操作系统也是自由软件和开放源代码发展中最著名的例子。严格来讲，Linux这个词本身只表示Linux内核，但在实际上人们已经习惯了用Linux来形容整个基于Linux内核，并且使用GNU 工程各种工具和数据库的操作系统。Linux得名于计算机业余爱好者Linus Torvalds。 -Linux is a Unix-computer" s operating system collectively. Linux operating system kernel is also the name of " Linux" . Linux operating system is also free software and open source development, the most famous example.
