46 function sets the protection bits of the address region bounded by

66 The range MUST be contiguous, and MUST NOT contain sub-maps.
67 .Sh IMPLEMENTATION NOTES
68 The function acquires a lock on the
70 for the duration, by calling
77 if the protection bits could be set successfully.
79 If a sub-map entry was encountered in the range,
80 .Dv KERN_INVALID_ARGUMENT
86 for an entry within the range,
87 .Dv KERN_PROTECTION_FAILURE
