sectors this pre-gap shall have. A pre-gap is written in the range of track

index 0 and contains zeros resp. silence. No bytes from the track source
|

will be read for writing the pre-gap.
|

This setting affects only CD SAO write runs.

Track 1 always has a pre-gap of at least 150 sectors. Further pre-gaps
|

are not mandatory for MMC compliance as long as track modes are not mixed.
|

Mode mixing is currently not supported by libburn.
|

The first track automatically gets a pre-gap of at least 150 sectors. Its
|
||||
size may be enlarged by this call. Further pre-gaps are demanded by MMC
|
||||
for tracks which follow tracks of a different mode. (But Mode mixing in
|
||||
CD SAO sessions is currently not supported by libburn.)

@param t The track to change

@param size Number of sectors in the pre-gap.

0 disables pre-gap, except for the first track.
