DESCRIPTION


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.

RETURN VALUES


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.

ERRORS


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.
