 This file contains the No Protocol (NOP) implementation of mutexes
32
 
33
 Title:
34
   NOP (Binary Semaphores)
35
 
36
 Resource Models Accepted:
37
   None
38
 
39
 Description:
40
   This module implement a mutex interface using extraction and insertion
41
   into scheduling queues.
42
 
43
 Exceptions raised:
44
   none
45
 
46
 Restrictions & special features:
47
   - This module is NOT Posix compliant
48
   - This module can manage any number of NOP mutexes.
49
   - A NOP mutex can be statically allocated. To do this, the init function
50
     have to define a macro that puts this information in the mutex
51
     descriptor: mutexlevel = <NOP resource level>; opt = NULL;
52
     for example, if the NOP module is registered at level 1, the macro is
53
     like:
54
     #define MUTEX_INITIALIZER {1,(void *)NULL}
