| Function | Description |
|---|---|
| slapi_op_reserved() | Allows a plug-in to recognize reserved default operations of the Directory Server. |
| slapi_operation_set_flag() | Sets a flag for the operation. |
| slapi_operation_clear_flag() | Clears a flag for the operation. |
| slapi_operation_is_flag_set() | Determines whether a flag is set in the operation. |
49.1. slapi_op_reserved()
This function allows a plug-in to recognize reserved default operations, such as the base-scope search on the root dse and the operations on the reserved naming contexts, for handling by the core Directory Server and not by the DIOP plug-in. This function allows you to implement a custom DIOP plug-in that does not affect the default behavior of the server. The code snippet below is a sample for a plug-in that handles the LDAP delete operation. The callback for the LDAP delete operation nullsuffix_delete will ignore all the LDAP delete operations on the reserved-naming contexts (such as cn=schema, cn=config, and cn=monitor).
#define PLUGIN_OPERATION_HANDLED 0
#define PLUGIN_OPERATION_IGNORED 1
static int nullsuffix_delete( Slapi_PBlock *pb )
{
if( slapi_op_reserved(pb) ){
return PLUGIN_OPERATION_IGNORED;
}
slapi_log_error( SLAPI_LOG_PLUGIN, PLUGIN_NAME,
"nullsuffix_delete\n" );
/* do the deletes */
send_ldap_result( pb, LDAP_SUCCESS, NULL, NULL, 0, NULL );
return PLUGIN_OPERATION_HANDLED;
}
#include "slapi-plugin.h" int slapi_op_reserved(Slapi_PBlock *pb);
This function takes the following parameter:
|
pb
| Parameter block. |
This function returns 0 if the operation is not reserved and a non-zero value if the operation is reserved.
