在Linux（RedHat）中，C函数malloc_stats（）显示的值与/proc/<；pid>/静态驻留内存大小

e、 g。 对于在Redhat linux中运行的进程 根据/proc/{pid}/stat的常驻页面*页面大小=>30GB

根据=>2.5 GB

知道为什么会这样吗

malloc\u stats

与用户领域中的

malloc

的实现相关联

pmap

或

/proc/self/stat

与虚拟地址空间及其在内核中的感知有关，它不仅随

malloc

调用的

mmap

而变化，还随

mmap

的其他调用而变化，包括与动态链接器相关的调用（

ld.so

）
