DPMI 0.9+ - ALLOCATE MEMORY BLOCK

AX = 0501h
BX:CX = size in bytes

Return:
CF clear if successful BX:CX = linear address of block SI:DI = memory block handle for resizing and freeing block CF set on error AX = error code (DPMI 1.0+) (8012h-8014h,8016h,8021h)(see #03143)

Notes: No selectors are allocated. The memory block is allocated unlocked (can be locked with AX=0600h). Allocations are often page granular (see AX=0604h). Under MS Windows 3.10 Enhanced mode with paging enabled, it is possible for this function to fail even if AX=0500h indicates that enough memory is available
