23 | OFFSET into the file FD describes according to PROT and FLAGS. If ADDR |
24 | is nonzero, it is the desired mapping address. If the MAP_FIXED bit is | |
25 | set in FLAGS, the mapping will be at ADDR exactly (which must be | |
26 | page-aligned); otherwise the system chooses a convenient nearby address. | |
