+ void rtems_mutex_try_lock(
+ rtems_mutex *mutex
+ );
+
+ void rtems_recursive_mutex_try_lock(
+ rtems_recursive_mutex *mutex

+
+DESCRIPTION:
+ Tries to lock the ``mutex``. In case the mutex is not locked, it will be
+ locked and the function returns with a return value of ``0``. If the mutex
+ is already locked, the function will return with a value of ``EBUSY``.
+
+NOTES:
+ This function must be called from thread context with interrupts enabled.
+
+ For recursively locking a mutex, please also see the notes for
+ :c:func:`rtems_mutex_lock` and :c:func:`rtems_recursive_mutex_lock`.
+
+ Each mutex lock operation must have a corresponding unlock operation.
