Pointers & Memory Synchronization

zugbruecke needs to translate pointers and synchronize memory between two processes. This section explains how this is done and when special memsync directives, extending regular ctypes syntax, are required.

Memory Synchronization in Detail

• Introduction to Memory Synchronization
  • Where is memory synchronized automatically?
  • Where is memsync required?
• The Memory Synchronization Protocol
  • A Simple Example
  • A Complex Example
  • String Buffers, Null-Terminated Strings and Unicode
  • Callbacks / Function Pointers
• The memsync attribute
  • Paths
  • Key: pointer, path to pointer
  • Key: length, path to length
  • Key: null, NULL-terminated string flag
  • Key: unic, Unicode character flag
  • Key: type, data type of pointer
