allocateMemory(size, BaseAddress OPTIONAL, Protection OPTIONAL): Allocates some memory into the target process
deAlloc(address, size OPTIONAL): Frees allocated memory

Can you focus on the Protection OPTIONAL parameter? Sample code is best
:?

Protection uses the Windows allocator constants for memory page protections which can be found here:
https://docs.microsoft.com/en-us/windows/win32/memory/memory-protection-constants
The default, when not given as it is optional, is PAGE_EXECUTE_READWRITE.
An example of that is:
| Code: |
allocateMemory(1024, 0x00400000, 0x40);
|
this will attempt to allocate 1024 bytes of memory at, or near, the address of 0x00400000 with the protection flags of 0x40 (PAGE_EXECUTE_READWRITE).
Keep in mind that both the base address and protection are optional parameters and can be ignored unless you require them for some reason. In the majority of cases, you should never need to use them though.
