/* 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.
