从自己的程序获取程序元数据

how can I bring to my C program variables the following values​​:

如何为我的C程序变量引入以下值:

• CPU used for the execution of the program, ie, how much processor is spent on that same program.

  用于执行程序的CPU(即在同一程序上花费多少处理器)。

• The execution time of the program, ie, how long it took to be completed.

  程序的执行时间，即完成所需的时间。

• The compiler warnings, ie, how can I put compiler warnings on string variables in my own program?

  编译器警告，例如，我如何在我自己的程序中把编译器警告放在字符串变量上?

• The size of my program to disk: the program spend my hard disk.

  我的程序到磁盘的大小:程序使用我的硬盘。

I find this very difficult to do and I do not know any way of doing it.

我发现这很难做到，我不知道怎么做。

Thanks to all in advance

提前谢谢大家

The compiler warnings of the executable is information that is only available after your program has been built. So I think it is not easily possible to pack this information statically to your "C program variables".

可执行程序的编译器警告是在您的程序建立之后才可用的信息。因此，我认为不可能将这些信息静态地打包到“C程序变量”中。

You could save this data to a file as an additional build step. For example write a program that executes the compiler and reads its output. This program would then either save the data to a file or give it the linker and tell it to pack it as ressource (but then you would be missing linker warnings).

您可以将这些数据保存到一个文件中作为额外的构建步骤。例如，编写一个执行编译器并读取其输出的程序。这个程序要么将数据保存到一个文件中，要么给它一个链接器，并告诉它把它作为ressource打包(但是你会丢失链接警告)。

Size, cpu usage and run time is information that can be fetched by the program at runtime. You can get the size of a file easily with the C library (fopen etc). Run time can be gotten by starting a timer at the startup of your application and right before exiting you read that timer to get the total run time. I think for cpu usage you have to ask the operating system (a quick google search for windows got me this)

大小、cpu使用率和运行时间是程序在运行时可以获取的信息。您可以通过C库(fopen等)轻松获得文件的大小。可以通过在应用程序启动时启动计时器来获得运行时间，并在退出之前读取计时器以获得总运行时间。我认为，对于cpu的使用，你必须询问操作系统(快速搜索谷歌windows就得到了这个)

[EDITED to include program execution time, filesize]

【编辑为包含程序执行时间、文件尺寸】

For windows only: here is some code that can be used to get some of what you want. This implementation returns only PeakWorkingSize, but I have included a commented copy of the struct containing all of the values you can obtain, with minor modifications. This will compile and build in ANSI C if you include the psapi.lib (part of windows SDK installation, freely down loadable here)

只适用于windows:这里有一些代码可以用来获得您想要的一些东西。这个实现只返回PeakWorkingSize，但是我已经包含了包含所有可以获得的值的结构体的注释副本，并进行了一些修改。如果包含psapi，这将在ANSI C中编译和构建。lib(部分windows SDK安装，可在此免费下载)

#include <windows.h>
#include <ansi_c.h>
#include <psapi.h>

time_t GetMemUsage(void);

int main(int argc, char *argv[])
{
    DWORD start, elapsed; // for program execution time
    size_t memory; //for cpu usage;
    DWORD  filesize=0; //for exe file size
    FILE *fp;
    char buf[260];
    int i;

    start = GetTickCount();

    sprintf(buf, ".\\%s", argv[0]);

    fp = fopen(buf, "r");

    filesize = GetFileSize(fp, NULL);

    for(i=0;i<1000000;i++); //so ticks will be more than zero

    memory = GetMemUsage();

    fclose(fp);

    elapsed = GetTickCount() - start; //note, possible rollover, 

    return 0;   
}

time_t GetMemUsage(void)
{
    HANDLE hProcess;
    PROCESS_MEMORY_COUNTERS pmc;
    DWORD processID = GetCurrentProcessId();

    hProcess = OpenProcess(  PROCESS_QUERY_INFORMATION |
                                    PROCESS_VM_READ,
                                    FALSE, processID );
    GetProcessMemoryInfo( hProcess, &pmc, sizeof(pmc));
    CloseHandle(hProcess);

//  typedef struct _PROCESS_MEMORY_COUNTERS {
//      DWORD cb;
//      DWORD PageFaultCount;
//      SIZE_T PeakWorkingSetSize;
//      SIZE_T WorkingSetSize;
//      SIZE_T QuotaPeakPagedPoolUsage;                             
//      SIZE_T QuotaPagedPoolUsage;
//      SIZE_T QuotaPeakNonPagedPoolUsage;
//      SIZE_T QuotaNonPagedPoolUsage;
//      SIZE_T PagefileUsage;
//      SIZE_T PeakPagefileUsage;
//  } PROCESS_MEMORY_COUNTERS;

typedef PROCESS_MEMORY_COUNTERS *PPROCESS_MEMORY_COUNTERS;

    return pmc.PeakWorkingSetSize;
}
