C语言怎么获得进程的PE文件信息

一、打印Sections信息。下面的程序打印出Windows_Graphics_Programming 1.1中第三个程序“Hello World Version 3:Create a Full-Screen Window"生成的可执行文件的Sections结构字节的信息

#include<stdio.h>
#include<windows.h>

char *strPath="C:/c1_hwv3/Debug/c1_hwv3.exe";

int main()
{
  IMAGE_DOS_HEADER myDosHeader;
  LONG e_lfanew;
  FILE *pFile;
  pFile=fopen(strPath,"rb+");

  fread(&myDosHeader,sizeof(IMAGE_DOS_HEADER),1,pFile);
  e_lfanew=myDosHeader.e_lfanew;

  IMAGE_FILE_HEADER myFileHeader;
  int nSectionCount;

  fseek(pFile,(e_lfanew+sizeof(DWORD)),SEEK_SET);
  fread(&myFileHeader,sizeof(IMAGE_FILE_HEADER),1,pFile);
  nSectionCount=myFileHeader.NumberOfSections;

  IMAGE_SECTION_HEADER *pmySectionHeader=
    (IMAGE_SECTION_HEADER *)calloc(nSectionCount,sizeof(IMAGE_SECTION_HEADER));
  fseek(pFile,(e_lfanew+sizeof(IMAGE_NT_HEADERS)),SEEK_SET);
  fread(pmySectionHeader,sizeof(IMAGE_SECTION_HEADER),nSectionCount,pFile);

  for(int i=0;i<nSectionCount;i++,pmySectionHeader++)
  {
    printf("Name: %s\n", pmySectionHeader->Name);
    printf("union_PhysicalAddress: %08x\n", pmySectionHeader->Misc.PhysicalAddress);
    printf("union_VirtualSize: %04x\n", pmySectionHeader->Misc.VirtualSize);
    printf("VirtualAddress: %08x\n", pmySectionHeader->VirtualAddress);
    printf("SizeOfRawData: %08x\n", pmySectionHeader->SizeOfRawData);
    printf("PointerToRawData: %04x\n", pmySectionHeader->PointerToRawData);
    printf("PointerToRelocations: %04x\n", pmySectionHeader->PointerToRelocations);
    printf("PointerToLinenumbers: %04x\n", pmySectionHeader->PointerToLinenumbers);
    printf("NumberOfRelocations: %04x\n", pmySectionHeader->NumberOfRelocations);
    printf("NumberOfLinenumbers: %04x\n", pmySectionHeader->NumberOfLinenumbers);
    printf("Charateristics: %04x\n", pmySectionHeader->Characteristics);
  }
//  pmySectionHeader-=m_nSectionCount;

  if(pmySectionHeader!=NULL)
  {
    free(pmySectionHeader);
    pmySectionHeader=NULL;
  }

  fclose(pFile);
  return 0;
}

运行程序打印出如下信息
