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: %sn", pmySectionHeader->Name); printf("union_PhysicalAddress: %08xn", pmySectionHeader->Misc.PhysicalAddress); printf("union_VirtualSize: %04xn", pmySectionHeader->Misc.VirtualSize); printf("VirtualAddress: %08xn", pmySectionHeader->VirtualAddress); printf("SizeOfRawData: %08xn", pmySectionHeader->SizeOfRawData); printf("PointerToRawData: %04xn", pmySectionHeader->PointerToRawData); printf("PointerToRelocations: %04xn", pmySectionHeader->PointerToRelocations); printf("PointerToLinenumbers: %04xn", pmySectionHeader->PointerToLinenumbers); printf("NumberOfRelocations: %04xn", pmySectionHeader->NumberOfRelocations); printf("NumberOfLinenumbers: %04xn", pmySectionHeader->NumberOfLinenumbers); printf("Charateristics: %04xn", 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
