See COPYRIGHT/LICENSE. +.SH NAME +ldap_result \- Wait for the result of an LDAP operation +.SH LIBRARY +OpenLDAP LDAP (libldap, \-lldap) +.SH SYNOPSIS +.nf +.ft B +#include <ldap.h> +.LP +.ft B +int ldap_result( LDAP *ld, int msgid, int all, + struct timeval *timeout, LDAPMessage **result ); + +int ldap_msgfree( LDAPMessage *msg ); + +int ldap_msgtype( LDAPMessage *msg ); + +int ldap_msgid( LDAPMessage *msg ); +.ft +.SH DESCRIPTION +The +.B ldap_result() +routine is used to wait for and return the result of +an operation previously initiated by one of the LDAP asynchronous +operation routines (e.g., +.BR ldap_search_ext (3), +.BR ldap_modify_ext (3), +etc.). Those routines all return \-1 in case of error, and an +invocation identifier upon successful initiation of the operation. The +invocation identifier is picked by the library and is guaranteed to be +unique across the LDAP session. It can be used to request the result +of a specific operation from +.B ldap_result() +through the \fImsgid\fP parameter. +.LP +The +.B ldap_result() +routine will block or not, depending upon the setting +of the \fItimeout\fP parameter. +If timeout is not a NULL pointer, it specifies a maximum +interval to wait for the selection to complete. If timeout +is a NULL pointer, the LDAP_OPT_TIMEOUT value set by +.BR ldap_set_option (3) +is used. With the default setting, +the select blocks indefinitely. To +effect a poll, the timeout argument should be a non-NULL +pointer, pointing to a zero-valued timeval structure. +To obtain the behavior of the default setting, bypassing any value set by +.BR ldap_set_option (3), +set to -1 the \fItv_sec\fP field of the \fItimeout\fP parameter. +See +.BR select (2) +for further details. +.LP +If the result of a specific operation is required, \fImsgid\fP should +be set to the invocation identifier returned when the operation was +initiated, otherwise LDAP_RES_ANY or LDAP_RES_UNSOLICITED should be +supplied to wait for any or unsolicited response. +.LP +The \fIall\fP parameter, if non-zero, causes +.B ldap_result() +to return all responses with msgid, otherwise only the +next response is returned. This is commonly used to obtain all +the responses of a search operation. +.LP +A search response is made up of zero or +more search entries, zero or more search references, and zero or +more extended partial responses followed by a search result. If +\fIall\fP is set to 0, search entries will be returned one at a +time as they come in, via separate calls to +.BR ldap_result() . +If it's set to 1, the search +response will only be returned in its entirety, i.e., after all entries, +all references, all extended partial responses, and the final search +result have been received. +.SH RETURN VALUE +Upon success, the type of the result received is returned and the +\fIresult\fP parameter will contain the result of the operation; +otherwise, the \fIresult\fP parameter is undefined. This +result should be passed to the LDAP parsing routines, +.BR ldap_first_message (3) +and friends, for interpretation. +.LP +The possible result types returned are: +.LP +.nf + LDAP_RES_BIND (0x61) + LDAP_RES_SEARCH_ENTRY (0x64) + LDAP_RES_SEARCH_REFERENCE (0x73) + LDAP_RES_SEARCH_RESULT (0x65) + LDAP_RES_MODIFY (0x67) + LDAP_RES_ADD (0x69) + LDAP_RES_DELETE (0x6b) + LDAP_RES_MODDN (0x6d) + LDAP_RES_COMPARE (0x6f) + LDAP_RES_EXTENDED (0x78) + LDAP_RES_INTERMEDIATE (0x79) +.fi +.LP +The +.B ldap_msgfree() +routine is used to free the memory allocated for +result(s) by +.B ldap_result() +or +.BR ldap_search_ext_s (3) +and friends. +It takes a pointer to the result or result chain to be freed and returns +the type of the last message in the chain. +If the parameter is NULL, the function does nothing and returns zero. +.LP +The +.B ldap_msgtype() +routine returns the type of a message. +.LP +The +.B ldap_msgid() +routine returns the message id of a message. +.SH ERRORS +.B ldap_result() +returns \-1 if something bad happens, and zero if the +timeout specified was exceeded. +.B ldap_msgtype() +and +.B ldap_msgid() +return \-1 on error. +.SH SEE ALSO +.BR ldap (3), +.BR ldap_first_message (3), +.BR select (2) +.SH ACKNOWLEDGEMENTS +.so ../Project diff --git a/doc/man/man3/ldap_result.3.links b/doc/man/man3/ldap_result.3.links new file mode 100644 index 0000000..1394c6c --- /dev/null +++ b/doc/man/man3/ldap_result.3.links @@ -0,0 +1,3 @@ +ldap_msgfree.3 +ldap_msgtype.3 +ldap_msgid.3 |
