The C language provides a very simple solution to overcome these limitations:dynamic memory allocationin which the memory is allocated at run-time, i. e., during the execution of a program. Dynamic memory management involves the use of pointers and four standard library functions, namely, malloc...
Rule Definition Dynamic heap memory allocation shall not be used. Rationale Dynamic memory allocation uses heap memory, which can lead to issues such as memory leaks, data inconsistency, memory exhaustion, and nondeterministic behavior. PolyspaceImplementation ...
memory allocated to the user begins after all of the block’s metadata. We must maintain the metadata like size and allocation status because we need it in the block’s header when we free the object. Optimization 1: While we need to maintain the size and allocation status, we only ...

The definition of strcpy is dangerous. The danger stems from the fact that strcpy fails to check that there is sufficient space in the character array that receives the copy, thereby increasing the chance of a buffer-overflow error. It is possible, however, to eliminate much of the danger by...
Second: use Error_IGNORE instead of NULL in the Task_create (or use an initialized Error Block). If you pass in NULL and there is a problem (e.g. memory allocation fails), the application halts instead of returning a NULL handle. ...
void *mem_heap_lo(void): Returns a generic pointer to the first valid byte in the heap. void *mem_heap_hi(void): Returns a generic pointer to the last valid byte in the heap. Caution: The definition of “last valid byte” may not be intuitive! If your heap is 8 bytes large, the...
For applications using data types such as video, it is possible to achieve compression ratios of 150:1 for Quarter Common Intermediate Format (QCIF) @15 fps over 64 Kbps (typically used in wireless video telephony applications) or 1080P High Definition (HD) @60 fps at 20 Mbps over broadband...
