  43   52  to be part of the string.
  44      -.SH USAGE
  45      -.sp
  46      -.LP
  47      -On most modern computer systems, you can \fInot\fR use a null pointer to
  48      -indicate a null string.  A null pointer is an error and results in an abort of
  49      -the program.  If you wish to indicate a null string, you must use a pointer
  50      -that points to an explicit null string.  On some machines and with some
  51      -implementations of the C programming language, a null pointer, if dereferenced,
  52      -would yield a null string.  Though often used, this practice is not always
  53      -portable. Programmers using a null pointer to represent an empty string should
  54      -be aware of this portability issue.  Even on machines where dereferencing a
  55      -null pointer does not cause an abort of the program, it does not necessarily
  56      -yield a null string.
