C语言读取PE文件信息（一）

接下来的内容来源于对该博客文章http://www.pediy.com/kssd/pediy06/pediy7006.htm的解析。

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),,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),,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=;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 ;
 }

运行程序打印出如下信息

Name: .text union_PhysicalAddress: 00022350 union_VirtualSize: 22350 VirtualAddress: 00001000 SizeOfRawData: 00023000 PointerToRawData: 1000 PointerToRelocations: 0000 PointerToLinenumbers: 0000 NumberOfRelocations: 0000 NumberOfLinenumbers: 0000 Charateristics: 60000020 Name: .rdata union_PhysicalAddress: 00001615 union_VirtualSize: 1615 VirtualAddress: 00024000 SizeOfRawData: 00002000 PointerToRawData: 24000 PointerToRelocations: 0000 PointerToLinenumbers: 0000 NumberOfRelocations: 0000 NumberOfLinenumbers: 0000 Charateristics: 40000040 Name: .data union_PhysicalAddress: 00005650 union_VirtualSize: 5650 VirtualAddress: 00026000 SizeOfRawData: 00004000 PointerToRawData: 26000 PointerToRelocations: 0000 PointerToLinenumbers: 0000 NumberOfRelocations: 0000 NumberOfLinenumbers: 0000 Charateristics: c0000040 Name: .idata union_PhysicalAddress: 00000b23 union_VirtualSize: 0b23 VirtualAddress: 0002c000 SizeOfRawData: 00001000 PointerToRawData: 2a000 PointerToRelocations: 0000 PointerToLinenumbers: 0000 NumberOfRelocations: 0000 NumberOfLinenumbers: 0000 Charateristics: c0000040 Name: .reloc union_PhysicalAddress: 00000f00 union_VirtualSize: 0f00 VirtualAddress: 0002d000 SizeOfRawData: 00001000 PointerToRawData: 2b000 PointerToRelocations: 0000 PointerToLinenumbers: 0000 NumberOfRelocations: 0000 NumberOfLinenumbers: 0000 Charateristics: 42000040
