Truxton file get size

This retrieves the size of the file as reported by the filesystem of the file. It corresponds to the [OSLength] column of the [File] table.

Syntax

uint64_t truxton_file_get_size( 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 size of the file as reported by the operating system. This can differ from the number of bytes written to the depot.

Sample

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

   if ( file != 0 )
   {
      return;
   }

   uint64_t file_size = truxton_file_get_size( file );

   printf( "Size is %" PRIu64 "\n", file_size );

   truxton_file_free( file );
}

Note, the PRIu64 in the sample code above is the new standard way of formatting a 64-bit 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.
