Parts
=====

* cmx-struct-refs

Helps to implement struct ref counting

Example:
   CMX_STRUCT_REFS_UNREF (ptr) {
       /* executed when ref count drops to 0 */
   }

* cmx-struct-shareable

Macros to implement uniform way how to treat struct's flow mutex
if enabled

Example:
  foo (struct Foo *ptr) {
      CMX_STRUCT_SHAREABLE_SYNCHRONIZE (ptr) {
      }
  }

* cmx-synchronize

Providing CMX_SYNCHRONIZE and CMX_RUN_ONCE allows you to simplify
(ie, hides) mutex operations into one keyword-look-like macro

Example:
  foo_init (void) {
      CMX_RUN_ONCE {
          foo = ...;
          bar = ...;
      }
  }

* cmx-local

Stores variable value, executes block and restore its value.
Macros can be serialized.

Example:
  foo () {
      int i = 1;
      int j = 1;

      CMX_LOCAL (i)
          printf ("%d %d\n", ++i, ++j); /* 2 2 */
      printf ("%d %d\n", ++i, ++j); /* 2 3 */
      CMX_LOCAL (i) CMX_LOCAL (j)
          printf ("%d %d\n", ++i, ++j); /* 3 4 */
      printf ("%d %d\n", ++i, ++j); /* 3 4 */
  }
