NAME

     vm_page_grab - returns a page from an object

SYNOPSIS

     #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);

DESCRIPTION

     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.

RETURN VALUES

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