RelSel Release a selector.

Inputs: AX = 0ff04h

BX = Selector.

Outputs: Carry set on error.

Errors: If an invalid selector is passed in BX, this function returns with carry set.

Notes: Use this function to release selectors allocated by GetSel or AliasSel.

ResMem Resize a previously allocated block of memory.

Inputs: AX = 0ff0dh

BX = Selector for block.

CX:DX = New size of block required in bytes.

Outputs: Carry set on error.

Errors: If an invalid selector is passed in BX 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 application is not affected as long as only the selector originally allocated with GetMem accesses the memory.
