- /* File : strend.c
- Author : Richard A. O'Keefe.
- Updated: 23 April 1984
- Defines: strend()
-
- strend(s) returns a character pointer to the NUL which ends s. That
- is, strend(s)-s == strlen(s). This is useful for adding things at
- the end of strings. It is redundant, because strchr(s,'\0') could
- be used instead, but this is clearer and faster.
- Beware: the asm version works only if strlen(s) < 65535.
