The ReadProcessMemory function reads memory in a specified process. The entire area to be read must be accessible, or the operation fails.
BOOL ReadProcessMemory(
HANDLE hProcess, |
// handle of the process whose memory is read |
LPCVOID lpBaseAddress, |
// address to start reading |
LPVOID lpBuffer, |
// address of buffer to place read data |
DWORD nSize, |
// number of bytes to read |
LPDWORD lpNumberOfBytesRead |
// address of number of bytes read |
); |
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
The function fails if the requested read operation crosses into an area of the process that is inaccessible.
ReadProcessMemory copies the data in the specified address range from the address space of the specified process into the specified buffer of the current process. Any process that has a handle with PROCESS_VM_READ access can call the function. The process whose address space is read is typically, but not necessarily, being debugged.
The entire area to be read must be accessible. If it is not, the function fails as noted previously.
