Problem conclusion

• The code has been changed to fix the problem. And z/OS C/C++
  Runtime Library Reference is updated as following:
  z/OS C/C++ Runtime Library Reference >
  Chapter - Library functions >
  mmap() - Map pages of memory >
  Add two new macros MAP_ANONYMOUS and MAP_ANON after __MAP_64
  in General description:
  
  MAP_ANONYMOUS
  The mapping is not backed by any file and the memory contents
  are initialized to zero. When MAP_ANONYMOUS is set, the fildes
  argument must be -1 and the off argument must
  be zero. MAP_ANONYMOUS can be used with any of the other
  Map_type options.
  
  MAP_ANON
  Synonym for MAP_ANONYMOUS.
  
  Add new parts in Usage notes:
  - When MAP_ANONYMOUS or MAP_ANON is specified, the fildes
  parameter must be -1.
  - When MAP_ANONYMOUS or MAP_ANON is specified, the off
  parameter must be 0.
  
  Append new description at the end of EINVAL description:
  When MAP_ANONYMOUS is specified, the fildes parameter must
  be -1.
  When MAP_ANONYMOUS is specified, the off parameter must be 0.
