/* File : strcat.c
Author : Richard A. O'Keefe.
Updated: 10 April 1984
Defines: strcat()
strcat(s, t) concatenates t on the end of s. There had better be
enough room in the space s points to; strcat has no way to tell.
Note that strcat has to search for the end of s, so if you are doing
a lot of concatenating it may be better to use strmov, e.g.
strmov(strmov(strmov(strmov(s,a),b),c),d)
rather than
strcat(strcat(strcat(strcpy(s,a),b),c),d).
strcat returns the old value of s.
*/
#include "strings.h"
char *strcat(register char *s, register const char *t)
{
char *save;
for (save = s; *s++; ) ;
for (--s; *s++ = *t++; ) ;
return save;
}
