Truxton file length

This tells you the size of the opened file in bytes.

Syntax

int64_t truxton_file_length( uint64_t file_handle );

Parameters

file_handle

The handle created by the truxton_file_open_id or truxton_file_open_md5 call.

Return value

The length of the file in bytes. If the file's contents were eliminated for any reason, the length will be zero because there are no contents to read.

Sample

int does_file_have_deep_philosophical_meaning( uint64_t truxton )
{
   uint64_t file = truxton_file_open_id( truxton, "5ed3aeb7-3da4-5f5c-8c8f-af5200000000" );

   if ( file != 0 )
   {
      return( 0 );
   }

   int return_value = 0;

   if ( truxton_file_length( file ) > 42 )
   {
      truxton_file_seek( file, 42, 0 );

      if ( truxton_file_tell( file ) == 42 )
      {
         return_value = 1;
      }
   }

   truxton_file_free( file );

   return( return_value );
}
