vm_page_grab — returns a page from an object
#include <sys/param.h> #include <vm/vm.h> #include <vm/vm_page.h> vm_page_t vm_page_grab(vm_object_t object, vm_pindex_t pindex, int allocflags);
The vm_page_grab() function returns the page at pindex from the given object. If the page exists and is busy, vm_page_grab() will sleep while 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.
If successful, vm_page_grab() returns the page; otherwise, NULL is returned.
