C++ (Cpp) pmem_partial_read示例

示例#1

文件： pmem.cpp 项目： KarlVogel/rekall

// This function uses as many pmem_partial_read() calls as necessary,
// to copy uio->resid bytes of physical memory from the physical address, as
// specified in uio->offset to the buffer in the uio.
static kern_return_t pmem_read_memory(struct uio *uio) {
  while (uio_resid(uio) > 0) {
    // Try to read as many times as necessary until the uio is full.
    pmem_partial_read(uio, uio_offset(uio),
                      uio_offset(uio) + uio_curriovlen(uio));
  }
  return KERN_SUCCESS;
}
