Truxton child file get size

This retrieves the file size of the child file object.

Syntax

uint64_t truxton_child_file_get_size( uint64_t child_handle );

Parameters

child_handle

The handle created by the truxton_child_file_create or truxton_file_create_child call.

Return

The size of the file as reported by the operating system.

Sample

void add_folder(uint64_t truxton, uint64_t parent_file)
{
   truxton_start_adding_files(truxton);

   uint64_t child = truxton_child_file_create(truxton);

   char id[40];

   truxton_file_get_id(parent_file, id, sizeof(id));
   truxton_child_file_set_parent_id(child, id);
   truxton_child_file_set_type(child, Type_Directory);
   truxton_child_file_set_name(child, "Custom Exploits Folder");

   FILETIME now;

   GetSystemTimeAsFileTime(&now);

   ULARGE_INTEGER ticks;

   ticks.LowPart = now.dwLowDateTime;
   ticks.HighPart = now.dwHighDateTime;

   truxton_child_file_set_created(child, ticks.QuadPart);
   truxton_child_file_set_accessed(child, ticks.QuadPart);
   truxton_child_file_set_modified(child, ticks.QuadPart);

   truxton_child_file_set_origin(child, ORIGIN_GENERATED);

   if ( truxton_child_file_save(child) == 0 )
   {
      printf( "Failed to add child to Truxton\n" );
   }
   else
   {
      uint64_t count = truxton_child_file_get_size(child_file);
      printf( "File size is %" PRIu64 "\n", count );
   }

   truxton_child_file_destroy(child);
}

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.
