Published C code for sorting (& other stuff)

[larry at JPL-VLSI.ARPA]

In Purdum's _C_Programmer's_Library_ from Cue (Que?) publishing company there's
a whole section on sorting.  C code is given for several types of sorts.  Other
sections have C code for other applications.

Does anyone know of other books with ready-made C code?  Seems a shame for us tobe always re-inventing the wheel.  I'd especially like to see a discussion of 
windowing and some useful code, even if only examples rather than a complete 
system.
