Truxton file create relation

This creates a relation object sourced from this file that you can use in the Relation API. A relation object is how you add records to the Relation table. The resulting object will automatically be associated with the file it was created from and with the media the file belongs to.

Syntax

uint64_t truxton_file_create_relation( uint64_t file_handle );

Parameters

file_handle

The handle created by the truxton_child_file_create or truxton_file_create_child call.

Return value

A handle to relation object.

Sample

void process_file(uint64_t truxton)
{
   uint64_t file = truxton_file_open_md5(truxton, "9ec8fb6095c35eff2b236863b7caaf10");

   uint64_t artifact_1 = truxton_file_create_artifact(file);

   truxton_artifact_set_type(artifact_1, ENTITY_TYPE_EMAIL_ADDRESS);
   truxton_artifact_set_value(artifact_1, "mdyson@cyberdynesystems.com" );
   truxton_artifact_save(artifact_1);

   uint64_t artifact_2 = truxton_file_create_artifact(file);

   truxton_artifact_set_type(artifact_2, ENTITY_TYPE_PERSON);
   truxton_artifact_set_value(artifact_2, "Miles Dyson" );
   truxton_artifact_save(artifact_2);

   uint64_t relation = truxton_file_create_relation(file);

   char identifier[40];

   truxton_artifact_get_id(artifact_1, identifier, sizeof(identifier));
   truxton_relation_set_a_id(relation, identifier);
   truxton_relation_set_a_type(relation, OBJECT_TYPE_ENTITY);

   truxton_artifact_get_id(artifact_2, identifier, sizeof(identifier));
   truxton_relation_set_b_id(relation, identifier);
   truxton_relation_set_b_type(relation, OBJECT_TYPE_ENTITY);

   truxton_relation_set_relation(relation, RELATION_MESSAGE_ADDRESS);

   truxton_relation_save(relation);

   truxton_relation_destroy(relation);
   truxton_artifact_destroy(artifact_1);
