void truxton_relation_get_b_id( uint64_t relation_handle, char * destination_string, size_t max_size );

Parameters

relation_handle

This handle comes from calling truxton_relation_create()

destination_string

The string to be written to.

max_size

The maximum number of characters that can be written to destination_string.

Sample

void dump_relation(uint64_t relation_handle)
{
   uint64_t value = 0;
   char guid_string[ 65 ];

   value = truxton_relation_get_a_type( relation_handle );
   truxton_relation_get_a_id( relation_handle, guid_string, sizeof( guid_string ) );
   printf( "A (%" PRIu64 ") %s is a ", value, guid_string );

   value = truxton_relation_get_relation( relation_handle );
   printf( "%" PRIu64 " of ", value );

   value = truxton_relation_get_b_type( relation_handle );
   truxton_relation_get_b_id( relation_handle, guid_string, sizeof( guid_string ) );
   printf( "B (%" PRIu64 ") %s is a ", value, guid_string );

   value = truxton_relation_get_source_type( relation_handle );
   truxton_relation_get_source_id( relation_handle, guid_string, sizeof( guid_string ) );

   printf( "Source (%" PRIu64 ") is %s\n", value, guid_string );
