CDseekblock(3dm)					      CDseekblock(3dm)

NAME
     CDseekblock, CDseekblockupdate - set read pointer for CD-ROM to start of
     specified block

SYNOPSIS
     #include <sys/types.h>
     #include <dmedia/cdaudio.h>

     unsigned long CDseekblock(CDPLAYER* cd, unsigned long block)

     unsigned long CDseekblockupdate(CDPLAYER* cd, unsigned long block)

PARAMETERS
     cd	     A pointer to the CDPLAYER structure representing the target CD-
	     ROM drive.

     block   The logical block number to set the pointer to.

RETURNED VALUE
     If successful, CDseekblock(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.

DESCRIPTION
     CDseekblock(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
     the specified logical block number.  Logical block numbers are returned
     by CDseekblock.  A location in absolute time code can be converted to a
     logical block number by CDmsftoblock(3dm).	 One logical block is one
     CDFRAME.

     CDseekblock(3dm) does not verify that the location is readable or update
     the status data until a subsequent call to CDreadda(3dm) has been made.
     CDseekblockupdate(3dm) is slower (it reads the new location), but
     guarantees that subsequent calls to CDgetstatus(3dm) are accurate.
