NAME

       ldap_result, ldap_msgfree - wait for and return LDAP operation result

SYNOPSIS

       cc[ flag... ] file... -lldap[ library... ]
       #include <lber.h>
       #include <ldap.h>

       int ldap_result(LDAP *ld, int msgid, int all,
	    struct bervalstruct timeval *timeout, LDAPMessage **result);

       int ldap_msgfree(LDAPMessage *msg);

DESCRIPTION

       The  ldap_result()  function is used to wait for and return the result of an operation previously initiated by one of the LDAP asynchronous
       operation functions , for example, ldap_search(3LDAP), and ldap_modify(3LDAP). Those functions 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	ldap_result()  through	the  msgid
       parameter.

       The  ldap_result()  function  will  block or not, depending upon the setting of the timeout 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  select  blocks  indefinitely.	To
       effect  a poll, the timeout argument should be a non-null pointer, pointing to a zero-valued timeval structure.	See select(3C) for further
       details.

       If the result of a specific operation is required, msgid should be set to the invocation identifier returned when the operation was  initi-
       ated,  otherwise  LDAP_RES_ANY should be supplied.  The all parameter only has meaning for search responses and is used to select whether a
       single entry of the search response should be returned, or all results of the search should be returned.

       A search response is made up of zero or more search entries followed by a search result.  If all is  set  to  0,  search  entries  will	be
       returned  one at a time as they come in, by means of separate calls to ldap_result(). If it is set to a non-zero value, the search response
       will only be returned in its entirety, that is, after all entries and the final search result have been received.

       Upon success, the type of the result received is returned and the result parameter will contain the result of the operation.   This  result
       should be passed to the LDAP parsing functions, (see ldap_first_entry(3LDAP)) for interpretation.

       The possible result types returned are:

	 #define LDAP_RES_BIND		0x61L
	 #define LDAP_RES_SEARCH_ENTRY	0x64L
	 #define LDAP_RES_SEARCH_RESULT 0x65L
	 #define LDAP_RES_MODIFY	0x67L
	 #define LDAP_RES_ADD		0x69L
	 #define LDAP_RES_DELETE	0x6bL
	 #define LDAP_RES_MODRDN	0x6dL
	 #define LDAP_RES_COMPARE	0x6fL

       The ldap_msgfree() function is used to free the memory allocated for a result by ldap_result() or ldap_search_s(3LDAP) functions.  It takes
       a pointer to the result to be freed and returns the type of the message it freed.

ERRORS

       The ldap_result() function returns -1 on error and 0 if the specified timeout was exceeded.

NOTES

       The ldap_result() function allocates memory for results that it receives.  The memory can be freed by calling ldap_msgfree.
