CDseektrack(3dm)CDseektrack(3dm)NAME
CDseektrack, CDseektrackupdate - set read pointer for CD-ROM to start of
specified track
SYNOPSIS
#include <sys/types.h>
#include <dmedia/cdaudio.h>
long CDseektrack(CDPLAYER* cd, int track)
long CDseektrackupdate(CDPLAYER* cd, int track)
PARAMETERS
cd A pointer to the CDPLAYER structure representing the target CD-
ROM drive.
track The track number the pointer is to be set to.
RETURNED VALUE
If successful, CDseektrack(3dm) returns the logical block number to which
the pointer has been set. Otherwise -1 is returned and errno is set to
indicate the error.
DESCRIPTIONCDseektrack(3dm) sets the pointer that indicates the starting point of
the next read of digital audio data from a CD-ROM. The specified track
is looked up in the disc's table of contents and the pointer is set to
the start of that track. The value is stored internally as a logical
block number. One logical block is one CDFRAME.
CDseektrack(3dm) does not verify that the location is readable or update
the status data until a subsequent call to CDreadda(3dm) has been made.
CDseektrackupdate(3dm) is slower (it reads the new location), but
guarantees that subsequent calls to CDgetstatus(3dm) are accurate.
