- /* 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.
