NERRO - Referenced by a user to obtain the current value of the internal error flag of SETER.

       To use nerro or c_nerro, load the NCAR Graphics libraries  ncarg, ncarg_gks, and ncarg_c,  preferably  in
       that order.

       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

       #include <ncarg/ncargC.h>

       The FORTRAN expression "NERRO(NERRF)" has the value of the internal error flag of SETER.  If its value is
       non-zero, this indicates that a prior recoverable error occurred and has not yet been cleared.  The
       argument NERRF is given the same value as the function reference; this is useful in some situations.

       The argument of NERRO is as follows:

       NERRF       (an  output variable of type INTEGER) - Receives the same value that is returned as the value
                   of the function itself.

       Use the ncargex command to see the following relevant examples: tseter, arex02.
