[alt.msdos.programmer] Unsetting environment vars in Turbo C

cs4g6ag@maccs.dcss.mcmaster.ca (Stephen M. Dunn) (03/14/90)

   Does anyone know how to unset an environment variable in Turbo C
2.0?  I've tried code of the form:

putenv ("foo=");

but it just changes the entry for foo to say

foo=

and I can't find any other functions that make changes to the environment.
Do I have to go in and play around with the environment pointers
directly?
