我正在尝试转储一个流程,比如calc.exe
当我运行我的程序时,我得到了
Program received signal SIGSEGV, Segmentation fault.
0x0000000000401640 in MiniDumpWriteDump ()
这是代码
#include <windows.h>
#include <dbghelp.h>
int main(){
HANDLE hFile = CreateFileA(
"calc.dmp",
GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_DELETE | FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL,
CREATE_ALWAYS,
FILE_ATTRIBUTE_NORMAL,
NULL
);
DWORD procID = 196;
HANDLE hProc = OpenProcess(
PROCESS_ALL_ACCESS,
FALSE,
procID
);
MiniDumpWriteDump(
hProc,
procID,
hFile,
MiniDumpWithFullMemory,
NULL,
NULL,
NULL
);
CloseHandle(hFile);
}
答案 0 :(得分:1)
您的示例适用于32位和64位窗口,但必须使用相同的“位数”进行编译(64位Windows上为64位,32位Windows上为32位)。
我只添加了一个窗口枚举和一个提供procID作为参数的方法。应检查返回值的函数是否有错误。
#include <windows.h>
#include <dbghelp.h>
#include <stdio.h>
#define TRYTO(b,a) if (!(a)) { \
fprintf(stderr,"Unable to " b "\n"); exit(1);}
static BOOL CALLBACK FunkyCallback(HWND hWnd, LPARAM lParam ){
char b[100]; RECT Rect;
DWORD pid;
if(!GetParent(hWnd)){
GetWindowText(hWnd, b, 99); GetWindowRect(hWnd,&Rect);
GetWindowThreadProcessId(hWnd, &pid);
printf("%li: %s left:%li top:%li\n",pid,b,Rect.left,Rect.top);
}
return TRUE;
}
int main(int argc, char ** argv){
HANDLE hFile;
DWORD procID;
HANDLE hProc;
if (argc > 1){
TRYTO("create file",(
hFile = CreateFile(
"proc.dmp",
GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_DELETE | FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL,
CREATE_ALWAYS,
FILE_ATTRIBUTE_NORMAL,
NULL
))!=INVALID_HANDLE_VALUE);
DWORD procID = atoi(argv[1]);
TRYTO("open process",(
hProc = OpenProcess(
PROCESS_ALL_ACCESS,
FALSE,
procID
)));
TRYTO("write dump",(
MiniDumpWriteDump(
hProc,
procID,
hFile,
MiniDumpNormal,
NULL,
NULL,
NULL
)));
fprintf(stderr,"Successfully created proc.dmp.\n",argv[0]);
CloseHandle(hFile);
} else {
EnumChildWindows(GetDesktopWindow(),FunkyCallback, 0);
fprintf(stderr,"Usage: %s procID\n",argv[0]);
}
}
使用Mingw64在Linux上测试。
Fedora Linux has packages here。我将64位dbghelp.dll
从Windows Server 2008 Windows / system32复制到源文件夹。 objdump -f
可以确认dll是64位还是32位。编译行类似于
/usr/bin/x86_64-w64-mingw32-gcc dmp.c -L. -l dbghelp -o dmp.exe
