LDAP_PARSE_RESULT(3)
NAME
ldap_parse_result - Parsing results
LIBRARY
OpenLDAP LDAP (libldap, -lldap)
SYNOPSIS
#include <ldap.h> int ldap_parse_result( LDAP *ld, LDAPMessage *result, int *errcodep, char **matcheddnp, char **errmsgp, char ***referralsp, LDAPControl ***serverctrlsp, int freeit ) int ldap_parse_sasl_bind_result( LDAP *ld, LDAPMessage *result, struct berval **servercredp, int freeit ) int ldap_parse_extended_result( LDAP *ld, LDAPMessage *result, char **retoidp, struct berval **retdatap, int freeit )
DESCRIPTION
These routines are used to extract information from a result message.
They will operate on the first result message in a chain of search
results (skipping past other message types). They take the result as
returned by a call to ldap_result(3), ldap_search_s(3) or
ldap_search_st(3). In addition to ldap_parse_result(), the routines
ldap_parse_sasl_bind_result() and ldap_parse_extended_result() are used
to get all the result information from SASL bind and extended operations.
The errcodep parameter will be filled in with the result code from the
result message.
The server might supply a matched DN string in the message indicating
how much of a name in a request was recognized. The matcheddnp parameter will be filled in with this string if supplied, else it will be
NULL. If a string is returned, it should be freed using ldap_memfree(3).
The errmsgp parameter will be filled in with the error message field
from the parsed message. This string should be freed using ldap_memfree(3).
The referralsp parameter will be filled in with an allocated array of
referral strings from the parsed message. This array should be freed
using ldap_memvfree(3). If no referrals were returned, *referralsp is
set to NULL.
The serverctrlsp parameter will be filled in with an allocated array of
controls copied from the parsed message. The array should be freed
using ldap_controls_free(3). If no controls were returned, *serverctrlsp is set to NULL.
The freeit parameter determines whether the parsed message is freed or
not after the extraction. Any non-zero value will make it free the message. The ldap_msgfree(3) routine can also be used to free the message
later.
For SASL bind results, the servercredp parameter will be filled in with an allocated berval structure containing the credentials from the server if present. The structure should be freed using ber_bvfree(3).
For extended results, the retoidp parameter will be filled in with the
dotted-OID text representation of the name of the extended operation
response. The string should be freed using ldap_memfree(3). If no OID
was returned, *retoidp is set to NULL.
For extended results, the retdatap parameter will be filled in with a
pointer to a berval structure containing the data from the extended
operation response. The structure should be freed using ber_bvfree(3).
If no data were returned, *retdatap is set to NULL.
For all the above result parameters, NULL values can be used in calls
in order to ignore certain fields.
ERRORS
Upon success LDAP_SUCCESS is returned. Otherwise the values of the
result parameters are undefined.
