  <assertion id="1" tag="ref:XSH6:{System Interfaces:munlock:DESCRIPTION}">
   The munlock() function shall unlock those whole pages containing any part of
   the address space of the process starting at address addr and continuing for
   len bytes, regardless of how many times mlock() has been called by the
   process for any of the pages in the specified range
  </assertion>
  <assertion id="2" tag="ref:XSH6:{System Interfaces:munlock:DESCRIPTION}">
   The implementation may require that addr be a multiple of {PAGESIZE}
  </assertion>
  <assertion id="3" tag="ref:XSH6:{System Interfaces:munlock:DESCRIPTION}">
   If any of the pages in the range specified to a call to munlock() are also
   mapped into the address spaces of other processes, any locks established on
   those pages by another process are unaffected by the call of this process to   munlock()
  </assertion>
  <assertion id="4" tag="ref:XSH6:{System Interfaces:munlock:DESCRIPTION}">
   If any of the pages in the range specified by a call to munlock() are also
   mapped into other portions of the address space of the calling process
   outside the range specified, any locks established on those pages via the
   other mappings are also unaffected by this call

   The munlock() function shall set errno = ENOMEM if some or all of the
