CDseek(3dm)CDseek(3dm)NAME
CDseek, CDseekupdate - set read pointer for CD-ROM to absolute time code
location
SYNOPSIS
#include <sys/types.h>
#include <dmedia/cdaudio.h>
long CDseek(CDPLAYER* cd, int min, int sec, int frame)
long CDseekupdate(CDPLAYER* cd, int min, int sec, int frame)
PARAMETERS
cd A pointer to the CDPLAYER structure representing the
target CD-ROM drive.
min,sec,frame The location in absolute time code to set the pointer to.
RETURNED VALUE
If successful, CDseek(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.
DESCRIPTIONCDseek(3dm) sets the pointer that indicates the starting point of the
next read of digital audio data from a CD-ROM. The pointer is set to an
absolute time code location specified in minutes, seconds and frames.
The value is stored internally as a logical block number. One logical
block is one CDFRAME.
CDseek(3dm) does not verify that the location is readable or update the
status data until a subsequent call to CDreadda(3dm) has been made.
CDseekupdate(3dm) is slower (it reads the new location), but guarantees
that subsequent calls to CDgetstatus(3dm) are accurate.
