VM_MAP_CHECK_PROTECTI... BSD Kernel Developer's ManualVM_MAP_CHECK_PROTECTI... NAME vm_map_check_protection -- check memory protection for a vm_map SYNOPSIS #include <sys/param.h> #include <vm/vm.h> #include <vm/vm_map.h> boolean_t vm_map_check_protection(vm_map_t map, vm_offset_t start, vm_offset_t end, vm_prot_t protection); DESCRIPTION The vm_map_check_protection() function asserts that the target map allows the specified privilege protection over the entire address range from start to end. The region MUST be contiguous; no holes are allowed. IMPLEMENTATION NOTES This code does not and SHOULD not check whether the contents of the re- gion are accessible. For example, a small file may be mapped into an ad- dress space which is significantly larger in size. RETURN VALUES The vm_map_check_protection() function returns TRUE if the privilege is allowed; if it is not allowed, or if any other error occurred, the value FALSE is returned.
