Memory Information

In Linux, system information is stored in the /proc directory of the system. Obtain the memory information from the files in the /proc directory in C and C++.

Example:

void getMemoryInfo()  
{  
    FILE *fp = fopen("/proc/meminfo", "r");    
    if(NULL == fp)     
        printf("failed to open meminfo\n");     
    char szTest[1000] = {0};    
    while(!feof(fp))    
    {    
        memset(szTest, 0, sizeof(szTest));    
        fgets(szTest, sizeof(szTest) - 1, fp);   
        printf("%s", szTest);    
    }    
    fclose(fp);   
}
