Summary of Data Types and Structures
Returns
One of the following values:
• 0 if the function successfully BER-encodes the computed attribute and adds it
to the BER element to be sent to the client.
• An LDAP error code if an error occurred.
Description
slapi_compute_output_t
BER-encodes a computed attribute and appends it to the BER element to be sent to
the client.
You do not need to define a function of this type. The server will pass a function of
this type your

slapi_compute_output_t
For example:
static int
my_compute_callback(computed_attr_context *c, char* type,
Slapi_Entry *e, slapi_compute_output_t outputfn)
{
...
int rc;
Slapi_Attr my_computed_attr;
...
/* Call the output function after created the computed
rc = (*outputfn) (c, &my_computed_attr, e);
...
}

Note that you do not need to define
