32 * reject.c - routines to write replication records to reject files.
33 * An Re struct is writted to a reject file if it cannot be propagated
34 * to a replica LDAP server.
41 #include <ac/stdlib.h>
42 #include <ac/string.h>
44 #include <ac/unistd.h>
62 * Write a replication record to a reject file. The reject file has the
63 * same name as the replica's private copy of the file but with ".rej"
64 * appended (e.g. "/usr/tmp/<hostname>:<port>.rej")
66 * If errmsg is non-NULL, use that as the error message in the reject
67 * file. Otherwise, use ldap_err2string( lderr ).
