allocate_memory_block function
Allocate a block of linear memory.
Declaration
function allocate_memory_block(size: LongInt): LongIntDescription
Allocates a block of linear memory.
Parameters:
- size:
- Size of requested linear memory block in bytes.
Returned values: blockhandle - the memory handle to this memory block. Linear address of the requested memory.
warning According to my DPMI docs this function is not implemented
correctly. Normally you should also get a blockhandle to this block after
successful operation. This handle can then be used to free the memory block
afterwards or use this handle for other purposes. Since the function isn't
implemented correctly, and doesn't return a blockhandle, the block can't be
deallocated and is hence unusable !
This function doesn't allocate any descriptors for this block, it's the
applications responsibility to allocate and initialize for accessing this
memory.
Errors
Check the int31error variable.
