NAME    [Toc]    [Back]

     DTframetotc - convert frame number	to timecode

SYNOPSIS    [Toc]    [Back]

     #include <sys/types.h>
     #include <dmedia/dataudio.h>

     void DTframetotc(unsigned long fr,	struct dttimecode* tc)

PARAMETERS    [Toc]    [Back]

     fr	  The frame number to be converted.

     tc	  A pointer to the struct dttimecode in	which to place the result.

DESCRIPTION    [Toc]    [Back]

     DTframetotc converts a DAT	frame number into a struct dttimecode which is
     defined as	follows	in dataudio.h :

	      struct dttimecode	{
		  unchar hhi:4,	hlo:4;
		  unchar mhi:4,	mlo:4;
		  unchar shi:4,	slo:4;
		  unchar fhi:4,	flo:4;
	      };


     Hours, minutes, seconds and frame number are each represented by 2	BCD
     digits.  This structure is	the same as a struct mtaudtimecode and can be
     passed as an argument to the MTSETAUDIO ioctl used	to search for time
     code locations on a tape.
