ResMemSO Resize a block of memory allocated via GetMemSO.

Inputs: AX = 0ff2dh

SI:DI = Selector:offset of block to resize

CX:DX = New size of block required in bytes

Outputs: Carry set on error else,

SI:DI = selector:offset of new memory block address.

Errors: If an invalid selector:offset is passed in SI:DI or not enough memory is available when increasing the block size, then this function returns carry set.

Notes: If the memory block cannot be resized in its current location, but a free block of memory of the new size exists, the memory is copied to a new block and the old one is released. The selector:offset will change if this occurs, so the SI:DI return value should be used to update all references and pointers to the memory block when this function is called.

ResMem32 Resize a previously allocated block of memory.

Inputs: AX = 0ff0eh

BX = Selector for block.

ECX = New size of block required in bytes.

Outputs: Carry set on error.

Errors: See ResMem

Notes: If the memory block cannot be resized in its current location, but a free block of memory of the new size exists, the memory is copied to a new block and the old one released. This is transparent to the application as long as only the selector originally allocated with GetMem is used to access the memory.
