NAME    [Toc]    [Back]

     vm_map_insert -- insert an object into a map

SYNOPSIS    [Toc]    [Back]

     #include <sys/param.h>
     #include <vm/vm.h>
     #include <vm/vm_map.h>

     int
     vm_map_insert(vm_map_t map, vm_object_t object, vm_ooffset_t offset,
	 vm_offset_t start, vm_offset_t end, vm_prot_t prot, vm_prot_t max,
	 int cow);

DESCRIPTION    [Toc]    [Back]

     The vm_map_insert() function inserts a mapping for the entire vm_object
     object into the target map map.

     The offset argument specifies the offset into the object at which to
     begin mapping.  The object's size should match that of the specified
     address range.

     The start and end arguments specify the bounds of the mapped object's
     window in the address space of map.

     The cow argment specifies the flags which should be propagated to the new
     entry, for example, to indicate that this is a copy-on-write mapping.

IMPLEMENTATION NOTES    [Toc]    [Back]

     This function implicity creates a new vm_map_entry by calling the internal
 function vm_map_entry_create().  This function may use the Giant lock
     to ensure that only a single thread is present in the function.

RETURN VALUES    [Toc]    [Back]

     The vm_map_insert() function returns KERN_SUCCESS if the mapping could be
     made successfully.

     Otherwise, KERN_INVALID_ADDRESS will be returned if the start of the
     range could not be found, or KERN_NO_SPACE if the range was found to be
     part of an existing entry or if it overlaps the end of the map.
