if cond

A conditional variable is a method for synchronizing between threads, which is used to automatically block a thread until it receives a cond signal or other special case, and the condition variable must be used in conjunction with the mutex when

This is a creation in Article, where the information may have evolved or changed. The main function of cond is to acquire a lock, and the Wait () method waits for a notification to proceed with the next lock release, which controls the appropriate

Case allows us to compare the values of many patterns until we find a matching--don't think of switch caseIEX ($) > x = 11IEX ($) > Case Ten Do... (+) > x, "1000"... (200) > _... (+) > End"1000"To pattern-match an existing variable, you need the ^

I. Problem solving and scope of applicationis primarily used to wait for a condition that may require another thread to satisfy this condition. The biggest difference between this and our usual pthread_mutex_lock is that the latter is generally

I. Differentiate the arm instruction set from the thumb Instruction Set first.The thumb command can be seen as a subset of arm commands in the form of compression. It is proposed for the code density problem. It has 16-bit code density, but it is
