2. Reading and writing sectors

The read and write functions are:

    unsigned char __fastcall__ dio_read (dhandle_t handle,
                                         sectnum_t sect_num,
                                         void *buffer);

This function will read the sector specified by sect_num into the memory location at buffer.

    unsigned char __fastcall__ dio_write (dhandle_t handle,
                                          sectnum_t sect_num,
                                          const void *buffer);

This function will write the memory contents at buffer to the sector specified by sect_num. No verify is performed.

    unsigned char __fastcall__ dio_write_verify (dhandle_t handle,
                                                 sectnum_t sect_num,
                                                 const void *buffer);

This function will write the memory contents at buffer to the sector specified by sect_num. A verification is performed.

Use the dio_query_sectsize function to query the size of a sector and the dio_query_sectcount function to query the number of available sectors.

All these functions will return 0 for success and an OS specific error code in case of failure.
