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_file_open_id or truxton_file_open_md5 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 );
   truxton_artifact_destroy( artifact_2 );
   truxton_file_free( file );
