7.8 Manipulating the CD block

List

Title Function specifications

Function Aperture and CD buffer partition connection

Function Name STM_ConnectCdbuf

No 8.1

Form

void STM_ConnectCdbuf (StmHn keystm, StmHn bufstm)

input

keystm	: Source stream handle
bufstm	: Connected stream handle (STM_CON_NULBUF to disconnect)

output

none

Function value

none

function

Connect the aperture and buffer partition in the CD block.

remarks

1. Reads from the aperture assigned to the connection source stream to the CD buffer partition assigned to the connection destination stream.

2. To return to the original settings, specify the same stream handle as the connection source.

3. Shows the connection when the stream key is set to the OR condition.
   

4. Only CD streams can be specified.

Function Moving CD buffer partition data

Function Name STM_MoveCdbuf

No 8.2. 8.2

Form

void STM_MoveCdbuf (StmHn src, Sint32 spos, Sint32 snum, StmHn dst)

input

src	: Source stream handle
spos	: Sector position (first sector is STM_CDBUF_TOP)
snum	: Number of sectors (STM_CDBUF_END up to the end)
dst	: Destination stream handle

output

none

Function value

none

function

Move sector data from the buffer partition in the CD block to the aperture.

remarks

1. Moves sector data from the CD buffer partition assigned to the source stream to the aperture assigned to the destination stream.
   

2. Only CD streams can be specified.
