/* The LDAP read-only data store is mmapped and trusted, because it
|
|
* takes higher privileges than tinyldap has to modify it.
|
|
* Strings are stored in it as ASCIIZ, so we can just operate on them
|
|
* after mapping the file into memory.
|
|
* However, we also need to be able to store binary data including
|
|
* 0 bytes, so we extend the format slightly. Zero-length strings don't
|
|
* happen in regular LDAP, so if the string starts with a 0 byte, the
|
|
* next four bytes are a little-endian 32-bit length value and after
|
|
* than come that many binary bytes.
|
|
* This means we need small wrappers around strlen and strcmp.
|
|
* These are those small wrappers. */
