 but some services are provided by the kernel itself:
 
-=== void        _sys_ukn() ===
+=== void '''_sys_ukn'''() ===
 Function executed in case of undefined syscall
 
-=== void         _proc_xyp( unsigned int* x,  unsigned int*,   unsigned int* p ) ===
+=== void '''_proc_xyp'''( unsigned int* x,  unsigned int*,   unsigned int* p ) ===
 This function returns the processor (x,y,p) identifiers.
 
-=== void         _task_exit() ===
+=== void '''_task_exit'''() ===
 The calling task goes to sleeping state, after printing an exit message.
 It is descheduled and enters the "not runable" mode.
 
- === void         _context_switch() ===
+ === void '''_context_switch'''() ===
 This function deschedules the calling task. It mask interrupts before calling the _ctx_switch, and restore it when the task is rescheduled.
 
- === unsigned int _local_task_id() ===
+ === unsigned int '''_local_task_id'''() ===
 Returns current task local index (amongst tasks running on a given processor).
 
- === unsigned int _global_task_id() ===
+ === unsigned int '''_global_task_id'''() ===
 Returns current task global index (amongst all tasks running on all processors).
 
-=== unsigned int _thread_id() ===
+=== unsigned int '''_thread_id'''() ===
 Returns current thread index (amongst all tasks in a given multi-tasks application).
 
- === unsigned int _procs_number( unsigned int  cluster_id, unsigned int* number ) ===
+ === unsigned int '''_procs_number'''( unsigned int  cluster_id, unsigned int* number ) ===
 Returns in buffer argument the number of processors in cluster specified by the cluster_id argument.
 
- === unsigned int _get_vobj_ptr( char* vspace_name,  char* vobj_name,  mapping_vobj_t**  pvobj ) ===
+ === unsigned int '''_get_vobj_ptr'''( char* vspace_name,  char* vobj_name,  mapping_vobj_t**  pvobj ) ===
 This function returns in the res_vobj argument a pointer on a vobj identified by the (vspace_name / vobj_name ) couple. 
 Returns 0 if success, >0 if not found
 
- === unsigned int _vobj_get_vbase( char* vspace_name,  char* vobj_name,  unsigned int* vobj_vbase ) ===
+ === unsigned int '''_vobj_get_vbase'''( char* vspace_name,  char* vobj_name,  unsigned int* vobj_vbase ) ===
 This function writes in vobj_base the virtual base address of a vobj  identified by the (vspace_name / vobj_name ) couple.
 Returns 0 if success, >0 if not found
 
- === unsigned int _vobj_get_length( char* vspace_name,  char* vobj_name,  unsigned int* vobj_length ) ===
+ === unsigned int '''_vobj_get_length'''( char* vspace_name,  char* vobj_name,  unsigned int* vobj_length ) ===
 This function writes in vobj_length the length of a vobj identified by the (vspace_name / vobj_name ) couple.
 Returns 0 if success, >0 if not found
 
- === unsigned int _get_xy_from_ptr( void* ptr,  unsigned int*  px,  unsigned int*  py ) ===
+ === unsigned int '''_get_xy_from_ptr'''( void* ptr,  unsigned int*  px,  unsigned int*  py ) ===
 This function returns in the (x,y) arguments the coordinates of the  cluster where is mapped the ptr virtual address. It use the _get_context_slot() function to get the calling task page table, and uses the _v2p_translate() function to obtain the physical address. Returns 0 if success, > 0 if ptr not mapped in the calling task vspace.
