通过本文主要向大家介绍了c语言进程,c语言进程间通信,c语言进程调度,进程调度算法 c语言,c语言进程控制等相关知识,希望对您有所帮助,也希望大家支持linkedu.com www.linkedu.com
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;
}
</div>
运行程序打印出如下信息
