slapi_compute_callback_t specifies the prototype for a callback function that is called by the server when generating a computed attribute. If you want to use computed attributes, you should write a function of this type.

Syntax

#include "slapi-plugin.h"
typedef int (*slapi_compute_callback_t)
(computed_attr_context *c, char* type,
Slapi_Entry *e, slapi_compute_output_t outputfn);

Parameters

The function has the following parameters:

c	Pointer to the computed_attr_context structure containing information relevant to the computed attribute.
type	Attribute type of the attribute to be generated.
e	Pointer to the Slapi_Entry structure representing the entry to be sent back to the client.
outputfn	Pointer to the slapi_compute_output_t function responsible for BER-encoding the computed attribute and for adding it to the BER element to be sent to the client.

Returns. One of the following values:

• -1 if the function is not responsible for generating the computed attribute.
• 0 if the function successfully generates the computed attribute.
• An LDAP error code if an error occurred.
