[英]How to find largest element value in array according to following code segment
[英]How to find data segment and code segment range in program
我的老師讓我在 Windows 系統上做這個任務。 你能幫我通過程序找到一些數據段和代碼段地址范圍嗎?
這些是可以幫助您的 Windows API。
//store the base address the loaded Module
dllImageBase = (char*)hModule; //suppose hModule is the handle to the loaded Module (.exe or .dll)
//get the address of NT Header
IMAGE_NT_HEADERS *pNtHdr = ImageNtHeader(hModule);
//after Nt headers comes the table of section, so get the addess of section table
IMAGE_SECTION_HEADER *pSectionHdr = (IMAGE_SECTION_HEADER *) (pNtHdr + 1);
ImageSectionInfo *pSectionInfo = NULL;
//iterate through the list of all sections, and check the section name in the if conditon. etc
for ( int i = 0 ; i < pNtHdr->FileHeader.NumberOfSections ; i++ )
{
char *name = (char*) pSectionHdr->Name;
if ( memcmp(name, ".data", 5) == 0 )
{
pSectionInfo = new ImageSectionInfo(".data");
pSectionInfo->SectionAddress = dllImageBase + pSectionHdr->VirtualAddress;
**//range of the data segment - something you're looking for**
pSectionInfo->SectionSize = pSectionHdr->Misc.VirtualSize;
break;
}
pSectionHdr++;
}
將 ImageSectionInfo 定義為,
struct ImageSectionInfo
{
char SectionName[IMAGE_SIZEOF_SHORT_NAME];//the macro is defined WinNT.h
char *SectionAddress;
int SectionSize;
ImageSectionInfo(const char* name)
{
strcpy(SectioName, name);
}
};
