strmov(dst, src) moves all the characters of src (including the
|
||||
closing NUL) to dst, and returns a pointer to the new closing NUL in
|
||||
dst. The similar UNIX routine strcpy returns the old value of dst,
|
||||
which I have never found useful. strmov(strmov(dst,a),b) moves a//b
|
||||
into dst, which seems useful.
