Truxton child file write

This API stored file contents in Truxton.

Syntax

uint64_t truxton_child_file_write( uint64_t child_handle, void * buffer, size_t buffer_size );

Parameters

child_handle

The handle created by the truxton_child_file_create call.

buffer

A pointer to the bytes to write to Truxton.

buffer_size

The number of bytes to write.

Return value

Zero on failure. If all of the bytes were successfully written to the file, buffer_size will be returned.

Sample

void add_text(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_ASCII_Text);
   truxton_child_file_set_name(child, "Hi.txt");

   FILETIME now;

   GetSystemTimePreciseAsFileTime(&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);

   truxton_child_file_begin_write(child);

   char * message = "Hello World\n";

   truxton_child_file_write( child, message, strlen(message));

   truxton_child_file_end_write( child );

   if ( truxton_child_file_save(child) == 0 )
   {
      printf( "Failed to add child to Truxton\n" );
   }

   truxton_child_file_destroy(child);
}
