Parameters

hProcess  IntPtr

A handle to a process.

The function allocates memory that can later be mapped within the virtual address space of this process.

The handle must have the VirtualMemoryOperation access right.

refNumberOfPages  IntPtr

The size of the physical memory to allocate, in pages.

To determine the page size of the computer, use the GetSystemInfo function. On output, this parameter receives the number of pages that are actually allocated, which might be less than the number requested.

pageArray  IntPtr

A pointer to an array to store the page frame numbers of the allocated memory.

The size of the array that is allocated should be at least the refNumberOfPages times the size of the ULONG_PTR data type.

Caution: Do not attempt to modify this buffer. It contains operating system data, and corruption could be catastrophic. The information in the buffer is not useful to an application.

Return Value

If the function fails, the return value is .
