Well,i''m a newer in programming. How can i get a large(in MB),easy-accessed,fast block in Win9x/NT memory?

malloc?....i beleive so.

so, include the header file for the malloc function, then take your variable and do allocate the amount of memory you want for it.

e.g. var1 = (type)malloc(size_of_memory_in_bytes);

hope that helps (or someone prooves me wrong. Which will probably be the case).

Which language? In C or C++ just the standard memory allocation functions work fine:

        void example1() // I guess c++ only, but I'm not sure{   BYTE * memblock;   memblock = new BYTE[NUMBER_OF_BYTES_YOU_WANT];   // do what you want with it   delete [] memblock;}void example2() // works in c too{   BYTE * memblock;   memblock = (BYTE *) malloc(NUMBER_OF_BYTES_YOU_WANT);   // do what you want with it   free(memblock);  }        

(Well, I have to type faster... sorry Sponge99 but when I started to reply there were no answers )

THANK YOU, Sponge99 and BitMaster
now i knew...

How many megabytes do you need? I''d suggest using VirtualAlloc and page management for anything over 4 MB...heaps slow down on Windows 3.1''s posterity because of the VMM architecture (methinks). Thankfully, that doesn''t happen on NT. But, I''d use VirtualAlloc anyway.

Using GlobalAlloc in the win32 enviorment always returns memory allocated on a qword boundary, which can be helpful.Also, with many memory management calls, the system allocates more then you ask for (to line up blocks of memory more efficiantly, no doubt GlobalAlloc ends on a qword boundary also), GlobalAlloc does the same thing, but you can also use the GlobalSize function to see the exact number of bytes allocated.Your program will not violate memory protection if you use the extra memory it allocates (unless you use more then what is returned by GlobalSize).
I still prefer malloc
