Defines: strend()
|
|
22 |
||
23 |
strend(s) returns a character pointer to the NUL which ends s. That
|
|
24 |
is, strend(s)-s == strlen(s). This is useful for adding things at
|
|
25 |
the end of strings. It is redundant, because strchr(s,'\0') could
|
|
26 |
be used instead, but this is clearer and faster.
|
|
27 |
Beware: the asm version works only if strlen(s) < 65535.
