Compiling the NIST Time Client

[Shriramana Sharma <samjnaa@gmail.com>]

Hello all.

I downloaded the source code for the NIST Time Client from 
ftp://time-a.nist.gov/pub/daytime and compiled it using make. I made the 
following changes to the source code to make it compile without errors but I 
want to verify here that I have not committed a blunder (though the program 
compiles and works properly).

I got:

samjnaa@linux:~/src/daytime> make nistime
cc -o tcp.o -c tcp_time_client.c
tcp_time_client.c: In function ‘main’:
tcp_time_client.c:172: warning: incompatible implicit declaration of built-in 
function ‘exit’
tcp_time_client.c:172: error: too few arguments to function ‘exit’

function ‘exit’
tcp_time_client.c:310: warning: incompatible implicit declaration of built-in 
function ‘exit’
make: *** [tcp.o] Error 1

So I replaced all occurrences of:

exit(); with return;
exit(0); with return 0;
exit(1); with return 1;

after which I got a clean compile and the program seems to work fine.

Converting exit to return seems a harmless operation but ever since I came to 
Linux I am somewhat paranoid about hacking anything myself without 
guidance...

Thanks.
