DESCRIPTION    [Toc]    [Back]

     The vm_page_grab() function returns the page at pindex from the given

     waiting for it.  If the page does not exist, it is allocated.

     If VM_ALLOC_RETRY is not set in allocflags and the function sleeps,
     either getting the page from the object or while allocating it, NULL is
     returned.

RETURN VALUES    [Toc]    [Back]

     If successful, vm_page_grab() returns the page; otherwise, NULL is
     returned.
