Create an aligned malloc and free function that enables memory allocation with the requirement that the returned memory address be divisible by a particular power of two. EXAMPLEThe function align_malloc (1000, 128) returns a memory address that is a multiple of 128 and refers to 1000 byte of memory.Memory allotted by align_malloc will be released by aligned_ free ().

Can you help with this problem of bounded buffer shared memory. There are two processes who share a common memory. One process is called the Producer process and the other one is called Consumer Process. The buffer size is 4. These are the sequence of steps happening. Stepwise please show the value of IN pointer, OUT pointer and processes in Buffer. Assume that initial values of IN and OUT buffer as zero. Step1: Producer Produces -> P1 Step 2 Producer Produces ->P2 Step3 Producer Produces ->P3 Step4 Consumer consumes P1 Step5- Consumer Consumes P2 Step6- Producer Produces P4 Step7- Producer Produces p5 Step7- Consumer consumes P4
