DTtctoframe(3dm)					      DTtctoframe(3dm)

NAME
     DTtctoframe - convert DAT timecode structure to DAT frame number.

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

     unsigned long DTtctoframe(struct dttimecode* tc)

PARAMETERS
     tc	  A pointer to the struct dttimecode to be converted.

RETURNED VALUE
     DTtctoframe returns the desired frame number.

DESCRIPTION
     DTtctotime converts a struct dttimecode representing a time in absolute
     time on a DAT into the corresponding DAT frame number.  Absolute time is
     a continuously incrementing time starting from 0 at the start of the
     tape.  A struct dttimecode 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;
	      };

     Frame numbers are much easier to compare than timecodes.
