> Why oh why were gets(), puts() and the other pre-stdio functions not quietly retired when stdio was invented? puts() is still used all the time. In fact, for the almost-simplest of programs:

#include <stdio.h>
int main(void) {
    printf("hi\n");
    return 0;
}

gcc 4.1.2 on my system generates the following:

sub    $0x8,%rsp
mov    $0x4005f8,%edi
callq  400430 <puts@plt>
xor    %eax,%eax
add    $0x8,%rsp
retq   

If you use anything more complicated than a constant static string it will actually call printf().

Well, yeah, but as the analogue of gets(), entirely redundant to fputs(), 
both should have gone if either do, and gets() certainly should have gone.

But it didn't.
