Field Documentation const void* params_dev_t::buffer   Buffer from which to write void* params_dev_t::buffer   Buffer into which to read uint32_t params_dev_t::length   Number of bytes to read uint64_t params_dev_t::offset   Offset of the first byte to write. Block devices (e.g. disk drives) must honour this; character devices (e.g. serial ports) may ignore this. page_array_t* params_dev_t::pages   Buffer from which to write page_array_t* params_dev_t::pages   Buffer into which to read The documentation for this union was generated from the following file: driver.h Post a comment From:
