passwd.c & login.c

[Frasca, Mario (NL33)]

Hi David,

       while (pwd != NULL) {
         if (pwd->pw_uid == uid) {
-          int i = strlen(nbuf1);
-          if(nbuf1[i-1]=='\n')
-            nbuf1[i-1] = 0;
+          char *p=strchr(nbuf1,'\n');
+          if(p) *p='\0';
           pwd->pw_passwd = crypt(nbuf1, salt);
         }  

yes, your suggestion is quite shorter.
I just took the corresponding code from login.c without questioning its
efficiency.  I'll never do it again ;-)

by the way: we had to correct login.c anyway: replace that `write-read` pair
for prompting for a password with getpass(<prompt>); since we're busy on
that source, we can as well change the \n-removal according to your
suggestion.

ciao,
Mario.
