After the last returned result the server sends + NSLCD_RESULT_END. If some error occurs (e.g. LDAP server unavailable, + error in the request, etc) the server terminates the connection to signal + an error condition (breaking the protocol). + + These are the available basic data types: + INT32 - 32-bit integer value + TYPE - a typed field that is transferred using sizeof() + STRING - a string length (32bit) followed by the string value (not + null-terminted) the string itself is assumed to be UTF-8 + STRINGLIST - a 32-bit number noting the number of strings followed by + the strings one at a time + + Furthermore the ADDRESS compound data type is defined as: + INT32 type of address: e.g. AF_INET or AF_INET6 + INT32 lenght of address + RAW the address itself + With the ADDRESSLIST using the same construct as with STRINGLIST. + + The protocol uses network byte order for all types. +*/ + +/* The current version of the protocol.
