windows分配内存给进程

Question

比如， 有某进程a和b, 我要限定a进程最高只能占用50m内存， b进程40m内存
如何做？

Answer 1

linux中可以，windows中好像不行吧？

Answer 2

windows那么不厚度，莫非要自己写个程序搞定？

Answer 3

用作业对象进行限制。
CreateJobObject AssignProcessToJobObject 然后SetInformationJobObject ，第二个参数写JobObjectBasicLimitInformation接着倒数第二个参数填入一个JOBOBJECT_BASIC_LIMIT_INFORMATION结构的缓冲区
typedef struct _JOBOBJECT_BASIC_LIMIT_INFORMATION {
  LARGE_INTEGER PerProcessUserTimeLimit;
  LARGE_INTEGER PerJobUserTimeLimit;
  DWORD         LimitFlags;
  SIZE_T        MinimumWorkingSetSize;//最小内存
  SIZE_T        MaximumWorkingSetSize;//最大内存
  DWORD         ActiveProcessLimit;
  ULONG_PTR     Affinity;
  DWORD         PriorityClass;
  DWORD         SchedulingClass;
} JOBOBJECT_BASIC_LIMIT_INFORMATION, *PJOBOBJECT_BASIC_LIMIT_INFORMATION;

//typedef enum _PROCESSINFOCLASS {

typedef struct _POOLED_USAGE_AND_LIMITS {

    SIZE_T PagefileLimit;
} POOLED_USAGE_AND_LIMITS;
typedef POOLED_USAGE_AND_LIMITS *PPOOLED_USAGE_AND_LIMITS;这个应该可以吧,我没试过~~~

Answer 5

SetProcessWorkingSetSize
一旦交换占用的内存到虚拟内存，会导致内存硬盘间频繁的页面交换吧。我觉得一般加载程序的时候使用这个函数较好。
