Firstly, I'd like to thank those who responded to my sort() inquiry.

We are putting together a way sort a database of records.  The database/file
may be quite large (10 to 300 MB or more(?)).  Now, of course it would be 
impossible to load it all into core and sort there, so we are going to need 
to look at the file as a series of segments, sort each segment and then merge 
all of the segments.

We received many lovely psort(), qsort(), etc... routines from the net.  I 
also discovered that there is a qsort(3C) in Unix itself.  We might use
that one in that it is supported (no jokes please) a could fast.

I cannot find a corrisponding "merge" routine (paste?) to use.  Is there
one in the Unix release that would be best?  

Does anyone have a general purpose merge() that would be good to use for this 
application?



P.S. Please point out any problems that you may see with this or that I might 
run into implementing this.


Thanks,

Mitchell
