Prototype
procedure GetMem(var P: ^dword; WantedSize: word);
Description Fetches memory from the memory heap.
Parameters - WantedSize: pointer to the fetched memory
- WantedSize: size in bytes of the dynamic variable to allocate
Returns Returns a pointer to the fetched memory (of “WantedSize” bytes) in P if success; Otherwise 0 (no free
blocks of memory are large enough).

Example
GetMem(ptr,20*sizeof(PBuffer)); // ptr will point to a memory block where
PBuffer is allocated
Notes None.
