Constants and pointers ( Pointers and constants ) -- Const-modified pointer confusing generally involves a pointer involved in a constant modified with const, which is easy to confuse with the head. A simple technique is to look from the right to the left, the following is an example: Const int * P1 = NULL ;// Method 1 Int const * P2 = NULL ;// Statement 2 Int * const P3 = NULL ;// If the value assignment statement is commented out and "// erro

　　On the Internet, I found a few blog posts about the Banker's algorithm, Mark down. The author is still good, easy to understand, more practical than simply speaking meaning.Turn from:Mushang's BlogRecently began to prepare for the computer four, basically did not encounter any problems, the feeling of computer four is the examination of the understanding of memory, the problem of the banker algorithm is in the computer four a few computational problems.Example 1.

Recently began to prepare for the computer level four, basically did not encounter any problems, I feel that the computer level four is to test the understanding of memory, the banker algorithm is a problem in the computer four of the few computational problems. Example 1. There are three types of resources (A,B,C) and five processes (P1,P2,P3,P4,P5) in the system, and the number of 17,B resources is the number of 6,c resources is 19. The status of th

operations in a loop to obtain a lock. Resolving deadlocks Consider a situation in which if a process obtains a lock, disconnects from Redis (possibly a process hangs up, or a network outage), and if there is no effective mechanism to release the lock, then other processes will be in a waiting state, i.e. "deadlock". When we use SETNX to obtain the lock, we set the value of the key lock.foo to the effective time of the lock, and when the process gets the lock, the other process will constantly
