I am posting this to the net at the request of a friend of mine.
Please mail any responses to this to me and I will forward it
through the proper channels.

With reference to cdpath you might try one of the following .....
This is not the actual login shells variable but it will give the
cdpath of a csh that you start up.
main()
{
int topipe[2];
char temp[256];
pipe( topipe );
if ( fork() == 0 ) {
dup2( topipe[1], 1);
close( topipe[0] );
close( topipe[1] );
execl("/bin/csh","pwd","-c","echo $cdpath");
}
close( topipe[1] );
read( topipe[0], temp, sizeof(temp) );
close( topipe[0] );
printf("%s", temp);
}
----------------------------------------------------------------
OR
----------------------------------------------------------------
#include <stdio.h>
main()
{
FILE *pwd,*popen();
char temp[256];
pwd = popen("csh -c 'echo $cdpath' ", "r");
fread( temp, sizeof( temp ), 1, pwd );
printf("%s\n", temp );
}
