Dummy for no thread-safe code.
libcoap library code. Invoke an app callback that has a return value, unlocking global_lock first.
Called when Locked (need to unlock over app call-back) Unlocked by thread free'ing off context
r | Return value from func . |
c | Context to unlock. |
func | app call-back function to invoke. |
failed | Code to execute on lock failure |
Definition at line 554 of file coap_threadsafe_internal.h.
#define coap_lock_check_locked | ( | c | ) | {} |
Dummy for no thread-safe code.
libcoap library code. Check that global_lock is locked.

#define coap_lock_init | ( | ) |
Dummy for no thread-safe code.
libcoap library code. Initialize the global_lock.

alt_lock, | |||
failed | |||
) | func |
Dummy for no thread-safe code.
libcoap library code. Lock an alternative lock. To prevent locking order issues, global_lock is unlocked, the alternative lock is locked and then global_lock is re-locked.
Called when Locked (need to unlock over locking of alternative lock)
c | Context. |
alt_lock | Alternative lock locking code. |
failed | Code to execute on lock failure. |

Dummy for no thread-safe code.
libcoap library code. Lock The global_lock.
Invoked when Not locked at all Locked, app call-back, call from app call-back Locked, app call-back, call from app call-back, app call-back, call from app call-back Result global_lock locked. global_lock not locked if libcoap not started and failed

must be code that skips doing the lock protected code.
