c// C语言实现获取内存信息并输出的示例// 实现代码示例

#include #include

void printMemoryInfo() { struct rusage usage; if (0==getrusage(RUSAGE_SELF, &usage)) { printf(Memory Usage:\n); printf( Maximum resident set size: %ld kilobytes\n, usage.ru_maxrss); printf( Start of process text segment: %p\n, usage.ru_textstart); printf( End of process text segment: %p\n, usage.ru_textend); printf( Start of process data segment: %p\n, usage.ru_datastart); printf( End of process data segment: %p\n, usage.ru_dataend); printf( Start of process stack: %p\n, usage.ru_stackstart); printf( End of process stack: %p\n, usage.ru_stackend); } else { perror(getrusage); }}

int main() { printMemoryInfo(); return 0;}

C语言实现获取内存信息并输出的实例

实现实例代码：

headfile.h

#include <stdio.h> #include <stdlib.h> #include <time.h> #define TRUE 1 #define FALSE 0 #define MAX 10000 typedef int KeyType; typedef int OtherType; typedef struct { KeyType key; OtherType other_data; }RecordType;

seek.cpp

#include "stdafx.h" #include "headfile.h" #include "windows.h" #include "conio.h " #include"WinBase.h" #include "Psapi.h" #pragma once #pragma message("Psapi.h --> Linking with Psapi.lib") #pragma comment(lib,"Psapi.lib") int Data[MAX]={0}; void produceData(int a[],int length) //给数组生成数据，用于随即查找 { time_t t; srand(time(&t)); for (int i=0;i<length;i++) { a[i]=rand()%length; } } void printData(int a[],int length) //打印数字，到控制台，每五个换一行 { for (int i=0;i<length;i++) { printf("%8d",a[i]); if (0==i%5) { printf("\n"); } } } double showMemoryInfo() { double MemorySize; //单位MB HANDLE handle=GetCurrentProcess(); PROCESS_MEMORY_COUNTERS pmc; GetProcessMemoryInfo(handle,&pmc,sizeof(pmc)); MemorySize=pmc.WorkingSetSize/1024; printf("内存使用: %8lf \n",MemorySize); //WorkingSetSize The current working set size, in bytes. return MemorySize; } void writeRecordtime(unsigned rTime)//将程序结果运行时间写入文件 { FILE *fpRecord=NULL; char *s="your programm running time is: "; char *c="ms "; if((fpRecord=fopen("record.txt","wt+"))==NULL) { printf("Cannot open file strike any key exit!"); getchar(); exit(1); } fprintf( fpRecord, "%s", s); fprintf( fpRecord, "%d", rTime); fprintf( fpRecord, "%s", c); fprintf( fpRecord, "\n"); fprintf( fpRecord, "your programm use %fMB size of memory!!!", showMemoryInfo()); fclose(fpRecord); } int _tmain(int argc, _TCHAR* argv[]) { produceData(Data,MAX); printData(Data,MAX); getchar(); return 0; }
