|
*Purpose:
|
||
|
|
* Collates up to n bytes of two strings for lexical order.
|

|
|
* Strings are collated on a character basis, not a byte basis.
|
||
|
|
* Case of characters is not considered.

|
|
*Entry:
|
||
|
|
* unsigned char *s1, *s2 = strings to collate
|
||
|
|
* size_t n = maximum number of bytes to collate
|
||
|
|
*
|
||
|
|
*Exit:
|
||
|
|
* returns <0 if s1 < s2
|
||
|
|
* returns 0 if s1 == s2
|
