Truxton file type get id

This returns the integer identifier for the file type. This corresponds to the [ID] column of the [FileType] table.

Syntax

uint64_t truxton_file_type_get_id( uint64_t file_type );

Parameters

file_type

The handle to the file type object. This handle comes from calling truxton_file_type_create().

Return value

The integer identifier for the file type.

Sample

void create_file_type( void )
{
   uint64_t truxton = truxton_create();

   uint64_t file_type = truxton_file_type_create( truxton );

   truxton_file_type_set_short_name( file_type, "My Type" );
   truxton_file_type_set_long_name( file_type, "A new custom type derived from XML" );
   truxton_file_type_set_parent_id( file_type, Type_XML );
   truxton_file_type_set_extension( file_type, "xm2" );
   truxton_file_type_set_mime_type( file_type, "text/xml" );

   if ( truxton_file_type_save( file_type ) == 0 )
   {
      printf( "Cannot save file type to the database.\n" );
   }

   uint64_t new_id = truxton_file_type_get_id( file_type );

   if ( new_id == 0 )
   {
      printf( "Failed to create new file type\n" );
   }
   else
   {
      printf( "Created new file type as id %" PRIu64 "\n", new_id );
   }

   truxton_file_type_destroy( file_type );
   truxton_destroy( truxton );
}

The PRIu64 in the sample code above is a standard way of formatting a 64-bit unsigned integer in C. Over the years, different compilers on different operating systems used different format specifiers for things, these PRI macros, along with some tricky string concatenation the compilers perform for you, allow you to maintain a single code base without a bunch of macro magic.
