Description

P is a variable of any pointer type. Size is an expression specifying the size in bytes of the dynamic variable to allocate. Access the newly allocated memory by dereferencing the pointer; that is, use P^.

If there isn't enough memory available to allocate the dynamic variable, an EOutOfMemory exception is raised.

Note: It is considered preferable to use the New and Dispose procedures rather than GetMem and FreeMem.
