Here's an excerpt from WinAPI reference: === cut === 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 cbRead, // number of bytes to read LPDWORD lpNumberOfBytesRead // address of number of bytes read ); Parameters hProcess Identifies an open handle of a process whose memory is read. The handle must have PROCESS_VM_READ access to the process. lpBaseAddress Points to the base address in the specified process to be read. Before any data transfer occurs, the system verifies that all data in the base address and memory of the specified size is accessible for read access. If this is the case, the function proceeds; otherwise, the function fails. lpBuffer Points to a buffer that receives the contents from the address space of the specified process. cbRead Specifies the requested number of bytes to read from the specified process. lpNumberOfBytesRead Points to the actual number of bytes transferred into the specified buffer. If lpNumberOfBytesRead is NULL, the parameter is ignored. Return Value If the function succeeds, the return value is TRUE. If the function fails, the return value is FALSE. 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. Remarks 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.
