  <assertion id="1" tag="ref:XSH6:{System Interfaces:mlock:DESCRIPTION}">
   The mlock() function shall cause those whole pages containing any part of
   the address space of the process starting at address addr and continuing for
   len bytes to be memory-resident until unlocked or until the process exits or
   execs another process image
  </assertion>
  <assertion id="2" tag="ref:XSH6:{System Interfaces:mlock:DESCRIPTION}">
   The implementation may require that addr be a multiple of {PAGESIZE}
  </assertion>
  <assertion id="3" tag="ref:XSH6:{System Interfaces:mlock:DESCRIPTION}">
   Upon successful return from mlock(), pages in the specified range shall be
   locked and memory-resident
  </assertion>

   The appropriate privilege is required to lock process memory with mlock()
  </assertion>

   Upon successful completion, the mlock() function shall return a value of
   zero
  </assertion>

   Upon unsuccessful completion, no change is made to any locks in the address
   space of the process

   Upon unsuccessful completion, the function shall return a value of -1
  </assertion>
  <assertion id="8" tag="ref:XSH6:{System Interfaces:mlock:ERRORS}">
   The mlock() function shall set errno = ENOMEM if some or all of the address
   range specified by the addr and len arguments does not correspond to valid
   mapped pages in the address space of the process
  </assertion>
  <assertion id="9" tag="ref:XSH6:{System Interfaces:mlock:ERRORS}">
   The mlock() function shall set errno = EAGAIN if some or all of the memory
   identified by the operation could not be locked when the call was made
  </assertion>

   The mlock() function may set errno = EINVAL if the addr argument is not a
   multiple of {PAGESIZE}
  </assertion>
  <assertion id="11" tag="ref:XSH6:{System Interfaces:mlock:ERRORS}">
   The mlock() function may set errno = ENOMEM if locking the pages mapped by
   the specified range would exceed an implementation-defined limit on the
   amount of memory that the process may lock
  </assertion>
  <assertion id="12" tag="ref:XSH6:{System Interfaces:mlock:ERRORS}">
   The mlock() function may set errno = EPERM if the calling process does not
   have the appropriate privilege to perform the requested operation
