Using a condition variable lets the consumer find that when the queue is empty it can just wait on the condition variable indicating that the queue has had something put into it. No polling - that thread does nothing until a producer puts something in the queue, then signals the condition t...

A mutex or condition variable is represented by two shared memory serialization structures that are maintained between Language Environment and the kernel: the shared memory mutex block (SMMX) and the shared memory condvar block (SMCV). The C/Language Environment pthread_mutex_ini...
Usage notes The _OPEN_SYS_MUTEX_EXT feature switch can be optionally included. If the feature is set, then significantly larger pthread_cond_t objects will be defined. The feature is used for the management of mutex and condition variables in shared memory. If the feature switch is set in ...

Let's say I have it like this: Whenever the average check failed percent is greater than 2% What will trigger the rule? Is it when the CPU and Ram hit X % of CPU usage? Anyone got a link, where you can read about all the conditions ?

Except in the case of [ETIMEDOUT], all these error checks shall act as if they were performed immediately at the beginning of processing for the function and shall cause an error return, in effect, prior to modifying the state of the mutex specified bymutexor the condition variable specified...
(32). In the following, the assumption is made that the oscillation frequency νis an independent variable that is identical to the peak feedback wavelength of the external-cavity filter. The threshold gain as a function of frequency is then determined by simultaneous solution of the magnitude ...
