flac dev - Sep 2004 - how to determine total time of a flac sound file?

How do I determine the total time of a flac sound file by examining the 
blocks and headers in the file?  I appreciate any help.

from the STREAMINFO block: if the total_samples field is not
0, then the length in seconds is total_samples / sample_rate.
if it is 0, the length of the stream is unknown.

you can use the metadata interface in libFLAC to get the values:
http://flac.sourceforge.net/api/group__flac__metadata__level0.html

or since the STREAMINFO block is always first you can get them
from absolute offsets; see http://flac.sourceforge.net/format.html
