Assembly Language Questions Medium
In Assembly Language programming, memory allocation and deallocation are typically done using system calls or specific instructions provided by the operating system.
To allocate memory, the programmer can use system calls such as "brk" or "sbrk" in Unix-like systems, or "HeapAlloc" or "VirtualAlloc" in Windows. These system calls allow the programmer to request a specific amount of memory from the operating system. The allocated memory is usually returned as a pointer to the starting address of the allocated block.
For deallocation, the programmer needs to explicitly release the allocated memory to prevent memory leaks. This is typically done using system calls such as "free" in Unix-like systems or "HeapFree" in Windows. The programmer needs to pass the pointer to the allocated memory block to the appropriate deallocation function, which then frees up the memory and makes it available for future allocations.
It is important to note that in Assembly Language programming, memory management is often more manual and low-level compared to higher-level languages. The programmer needs to keep track of allocated memory blocks and ensure proper deallocation to avoid memory leaks or accessing invalid memory locations.
