It is also possible to call pkey_mprotect with a key value of -1, in which case it will behave in the same way as mprotect. The mprotect() function changes the access protections on the mappings specified by the len up to the next multiple of the page size as returned by sysconf(), to be that specified by prot. Legitimate values for prot are the same as those permitted for mprotect() and are defined in : PROT_READ page can be read PROT_WRITE page can be mprotect() changes protection for the calling process's memory page(s) containing any part of the address range in the interval [addr, addr+len-1]. addr must be aligned to a page boundary.
