Expand description
Error type for Mutex::try_lock
.
See ResultCode
for all result codes and generic descriptions.
Variants
NoAccess
Invalid object access.
BadContext
CPU Lock is active, or the current context is not a task context.
Timeout
WouldDeadlock
The current task already owns the mutex.
BadParam
The mutex was created with the protocol attribute having the value
Ceiling
and the current task’s priority is higher than the
mutex’s priority ceiling.
Abandoned
The previous owning task exited while holding the mutex lock. The current task shall hold the mutex lock, but is up to make the state consistent.
