Cgo内存管理

Valgrind安装和使用

cd valgrind-3.9.0/
./configure
make
make install

方法二：

sudo apt-get install valgrind

使用：

valgrind --tool=memcheck --leak-check=full valgrind_demo
valgrind --leak-check=full ./xxx

打印内存信息：

var m runtime.MemStats
runtime.ReadMemStats(&m)
log.Printf("Alloc = %v TotalAlloc = %v Sys = %v NumGC = %v\n", m.Alloc/1024, m.TotalAlloc/1024, m.Sys/1024, m.NumGC)
