This code seems to be crashing , can anyone help why
Code:
#include <windows.h>
#include <stdio.h>
//const char findme[8] = "PRIVMSG";
int main()
{
HANDLE ThisProc = OpenProcess(PROCESS_ALL_ACCESS,true,GetCurrentProcessId());
MEMORY_BASIC_INFORMATION mbi;
SYSTEM_INFO si;
GetSystemInfo(&si);
DWORD dwStart = 0;
SIZE_T v;
char *p;
DWORD lpRead;
const char* regionp;
BYTE s = 't';
char *memchrp;
int memcmpr;
const char findme[8] = "PRIVMSG";
HANDLE Term;
while(dwStart < (DWORD)si.lpMaximumApplicationAddress)
{
v = VirtualQueryEx(ThisProc,
(void *)dwStart,
&mbi,
sizeof(MEMORY_BASIC_INFORMATION));
if(v == 0)
{
printf("%s\n","breaking");
break;
}
if(mbi.State == MEM_COMMIT)
{
printf("%s\n","mem_commit");
p = (char *)malloc(mbi.RegionSize);
printf("Memory at %02x, size %d\n",
mbi.BaseAddress,
mbi.RegionSize);
if(ReadProcessMemory(ThisProc,(void *)dwStart,p,mbi.RegionSize,&lpRead))
{
const char* offset = regionp;
while ((offset = (const char*)memchr(offset, findme[0], regionp+mbi.RegionSize-offset)) != 0)
{
if (memcmp(offset, findme, 7) == 0)
{
printf("%s\n","found");
Sleep(5000);
break;
}
++offset;
}
}
}
if(dwStart + mbi.RegionSize < dwStart)
{
printf("%s\n","breaking");
break;
}
if(mbi.RegionSize != lpRead)
{
printf("Not enough bytes read %d != %d\n",mbi.RegionSize,lpRead);
}
dwStart += mbi.RegionSize;
Sleep(5);
}
