NTSTATUS NtMapViewOfVlmSection( IN HANDLE SectionHandle, IN HANDLE ProcessHandle, IN OUT PVOID64 *BaseAddress, IN OUT PULONGLONG SectionOffset OPTIONAL, IN OUT PULONGLONG ViewSize, IN ULONG AllocationType, IN ULONG Protect ); Routine Description: This function maps a view in the specified subject process to the section object. Arguments: SectionHandle - Supplies an open handle to a section object. ProcessHandle - Supplies an open handle to a process object. BaseAddress - Supplies a pointer to a variable that will receive the base address of the view. If the initial value of this argument is not null, then the view will be allocated starting at the specified virtual address rounded down to the next 64kb address boundary. If the initial value of this argument is null, then the operating system will determine where to allocate the view using the information specified by the ZeroBits argument value and the section allocation attributes (i.e. based and tiled). SectionOffset - Supplies the offset from the beginning of the section to the view in bytes. This value is rounded down to the next host page size boundary. ViewSize - Supplies a pointer to a variable that will receive the actual size in bytes of the view. If the value of this argument is zero, then a view of the section will be mapped starting at the specified section offset and continuing to the end of the section. Otherwise the initial value of this argument specifies the size of the view in bytes and is rounded up to the next host page size boundary. AllocationType - Supplies the type of allocation. Only 0 is valid. Protect - Supplies the protection desired for the region of initially committed pages. Protect Values PAGE_NOACCESS - No access to the committed region of pages is allowed. An attempt to read, write, or execute the committed region results in an access violation (i.e. a GP fault). PAGE_READONLY - Read only and execute access to the committed region of pages is allowed. An attempt to write the committed region results in an access violation. PAGE_READWRITE - Read, write, and execute access to the region of committed pages is allowed. If write access to the underlying section is allowed, then a single copy of the pages are shared. Otherwise the pages are shared read only/copy on write. Return Value: Returns the status.
