.dvalloc (Allocate Memory)
The .dvalloc command causes Windows to allocate additional memory to the target process.
.dvalloc [Options] Size
Parameters
Options Can be any number of the following options:
/b **** BaseAddress
Specifies the virtual address of the beginning of the allocation.
/r
Reserves the memory in the virtual address space but does not actually allocate any physical memory. If this option is used, the debugger calls VirtualAllocEx with the flAllocationType parameter equal to MEM_RESERVE. If this option is not used, the value MEM_COMMIT | MEM_RESERVE is used. See the Microsoft Windows SDK for details.
Size
Specifies the amount of memory to be allocated, in bytes. The amount of memory available to the program will equal Size. The amount of memory actually used may be slightly larger, since it is always a whole number of pages.
