AGGETR - Allows a user program to retrieve the real value of a single parameter.

       To  use AGGETR or c_aggetr, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in
       that order.  To get smoother curves, drawn using spline interpolation, also load libdashsmth.o.  Or,  you
       can  use the ncargf77 command to compile your program and load the above libraries, then, to get smoother
       curves, use the -dashsmth option.

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

       #include <ncarg/ncargC.h>

       void c_aggetr (char *tpgn, float *fusr)

       TPGN        (an input expression of type CHARACTER) is a parameter identifier, as described in the AGGETP
                   man  page. If a group of more than one parameter is specified, only the first element of that
                   group will be retrieved by the call.

       FUSR        (an output variable of type REAL) receives the real value of the parameter specified by TPGN.

       CALL AGGETR (TPGN,FUSR)

       This routine allows you to retrieve the current value of Autograph parameters.  For a  complete  list  of
       parameters available in this utility, see the autograph_params man page.
