gets and terminating \n

[Billoud Bernard]

Hello,

I have glibc 2.1.3 under linux, and the standard irix libc under sgi.

This is a short code using gets.
It does not behave the same under linux and sgi...

The '\n' character is not removed under linux, while it is under sgi.


#include <stdio.h>

void main (void){
  char foo[30]; 
  printf (">");
  gets (foo);
  printf ("\n>>%s>>\n", foo);
}

sgi output :
------------------------
abikini 102% gcc -o toto toto.c
toto.c: In function `main':
toto.c:3: warning: return type of `main' is not `int'
abikini 103% toto
>eric

>>eric>>
------------------------

linux output :
------------------------
address@hidden clustalw1.81]$ gcc -o toto toto.c
toto.c: In function `main':
toto.c:3: warning: return type of `main' is not `int'
/tmp/ccEMPuD8.o: In function `main':
/tmp/ccEMPuD8.o(.text+0x1e): the `gets' function is dangerous and should not be 
used.
address@hidden clustalw1.81]$ toto
>eric
 
>>eric
>>
------------------------

After having made a "man gets", I think that sgi has the right
solution.

Sincerely

Bernard Billoud
