Application code can request a memory block from a partition by calling OSMemGet() as shown in Listing 17-3. The code assumes that the partition was already created.

L17-3(1)The memory partition control block must be accessible by all tasks or ISRs that will be using the partition. L17-3

(2)Simply call OSMemGet() to obtain a memory block from the desired partition. A pointer to the allocated memory block is returned. This is similar to malloc(), except that the memory block comes from a pool that is guaranteed to not fragment. Also, it’s assumed that your application knows the size of each block so it doesn’t overflow the block with data.

L17-3(3)It is important to examine the returned error code to ensure that there are free memory blocks and that the application can start putting content in the memory blocks.
