/* Map addresses starting near ADDR and extending for LEN bytes. from

OFFSET into the file FD describes according to PROT and FLAGS. If ADDR
|
||
|
|
is nonzero, it is the desired mapping address. If the MAP_FIXED bit is
|
||
|
|
set in FLAGS, the mapping will be at ADDR exactly (which must be
|
||
|
|
page-aligned); otherwise the system chooses a convenient nearby address.
|
||
|
|
The return value is the actual mapping address chosen or (caddr_t) -1
|
||
|
|
for errors (in which case `errno' is set). A successful `mmap' call
|
||
|
|
deallocates any previous mapping for the affected region. */
