DTframetotc(3dm)

NAME
     DTframetotc - convert frame number to timecode

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

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

PARAMETERS
     fr   The frame number to be converted.

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

DESCRIPTION
     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.
