ldap_count_messages() is used to count the number of messages that remain in a chain of results if called with a message, entry, or reference returned by ldap_first_message(), ldap_next_message(), ldap_first_entry(), ldap_next_entry(), ldap_first_reference(), and ldap_next_reference()

ldap_first_message() and ldap_next_message() functions are used to step through the list of messages in a result chain returned by ldap_result().

ldap_msgtype() function returns the type of an LDAP message.

ldap_first_message() and ldap_next_message() return LDAPMessage which can include referral messages, entry messages and result messages.

ldap_count_messages() returns the number of messages contained in a chain of results.

ldap_first_message() and ldap_next_message() return NULL when no more messages exist. NULL is also returned if an error occurs while stepping through the entries, in which case the error parameters in the session handle ld will be set to indicate the error.
