Implements (in lock_ops.h & lock_alloc.h):
|
|
|
|
simple locks:
|
|
-------------
|
|
type: gen_lock_t
|
|
gen_lock_t* lock_alloc(); - allocates a lock in shared mem.
|
|
gen_lock_t* lock_init(gen_lock_t* lock); - inits the lock
|
|
void lock_destroy(gen_lock_t* lock); - removes the lock (e.g sysv rmid)
|
|
void lock_dealloc(gen_lock_t* lock); - deallocates the lock's shared m.
|
|
void lock_get(gen_lock_t* lock); - lock (mutex down)
|
|
void lock_release(gen_lock_t* lock); - unlock (mutex up)
|
|
|
|
lock sets:
|
|
----------
|
|
type: gen_lock_set_t
|
|
gen_lock_set_t* lock_set_alloc(no) - allocs a lock set in shm.
|
|
gen_lock_set_t* lock_set_init(gen_lock_set_t* set); - inits the lock set
|
|
void lock_set_destroy(gen_lock_set_t* s); - removes the lock set
|
|
void lock_set_dealloc(gen_lock_set_t* s); - deallocs the lock set shm.
|
|
void lock_set_get(gen_lock_set_t* s, int i); - locks sem i from the set
|
|
void lock_set_release(gen_lock_set_t* s, int i) - unlocks sem i from the set
|
|
|
|
WARNING: - lock_set_init may fail for large number of sems (e.g. sysv).
|
|
- signals are not treated! (some locks are "awakened" by the signals)
