Description
Allocates memory from the current process’s memory pool to
the current thread’s virtual segment.
Frees physical memory associated with the calling thread’s
virtual segment.
Creates a handle for an area of memory in the process’s virtual
segment.
Deletes a memory handle created with
CreateRtMemoryHandle.
Maps a memory area, previously created by another process
using CreateRtMemoryHandle, into the current thread’s
memory space.
Maps a physical memory area, defined by its absolute address
and contiguous length before any translation imposed by the
paging system, into the current process’ virtual segment.
Returns the physical address for a valid buffer described by the
call parameters.
Returns the number of bytes in a previously allocated segment.
Creates a heap object by allocating a segment of cbHeapSize
bytes (plus overhead) and creating the heap structure in this
segment.
Deletes a heap object, given its handle. Any flat-model
mappings are deleted.
Allocates a memory buffer from a heap object and returns a
pointer to the caller.
Returns a previously-allocated buffer to its heap.
Returns a structure containing information about a heap object.
Returns the allocated size of a buffer previously allocated from
a heap.
Copies data directly between RT memory objects.
