__dpmi_allocate_dos_memory
==========================

Syntax
------

     #include <dpmi.h>
     
     int __dpmi_allocate_dos_memory(int _paragraphs, int *_ret_selector_or_max);

Description
-----------

Please refer to DPMI Specification: for details on DPMI function   
call operation.  Also see DPMI Overview: for general information.   

DPMI function AX = 0x0100

This function allocates DOS memory.  You pass it the number of
paragraphs ((bytes+15)>>4) to allocate.  If it succeeds, it returns a
segment (dos-style) and fills in _RET_SELECTOR_OR_MAX with a selector
(protected-mode) that you can use to reference the same memory.  Note
that it's the selector you use to free the block, not the segment.

Return Value
------------

-1 on error, else the segment [0000..FFFF].
