/* 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.
