VM_MAP_PROTECT(9)        BSD Kernel Developer's Manual       VM_MAP_PROTECT(9)

NAME
     vm_map_protect — apply protection bits to a virtual memory region

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

     int
     vm_map_protect(vm_map_t map, vm_offset_t start, vm_offset_t end,
         vm_prot_t new_prot, boolean_t set_max);

DESCRIPTION
     The vm_map_protect() function sets the protection bits of the address
     region bounded by start and end within the map map to new_prot.

     If set_max is TRUE, new_prot is treated as the new max_protection setting
     for each underlying entry.  Otherwise, only the protection field is
     affected.

     The range MUST be contiguous, and MUST NOT contain sub-maps.

IMPLEMENTATION NOTES
     The function acquires a lock on the map for the duration, by calling
     vm_map_lock(9).

RETURN VALUES
     The vm_map_protect() function returns KERN_SUCCESS if the protection bits
     could be set successfully.

     If a sub-map entry was encountered in the range, KERN_INVALID_ARGUMENT is
     returned.  If the value of new_prot would exceed max_protection for an
     entry within the range, KERN_PROTECTION_FAILURE is returned.
