NAME

       TDGETR - Retrieves the real value of a Tdpack parameter.

SYNOPSIS

       CALL TDGETR (PNAM,RVAL)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_tdgetr (char *pnam, float *rval)

DESCRIPTION

       The arguments of TDGETR are as follows:

       PNAM    (an input constant or variable of type CHARACTER) - The name of the parameter that
               you want to retrieve.  The character string can be of any length, but only the
               first three characters of it will be examined.

       RVAL    (an output variable of type REAL) - A real variable to receive the desired
               parameter value.  If the internal parameter is of type REAL and has the value "r",
               RVAL will be given the value "r"; if the internal parameter is of type INTEGER and
               has the value "i", RVAL will be given the value "REAL(i)".

C-BINDING DESCRIPTION

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

USAGE

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

ACCESS

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

MESSAGES

       See the "tdpack" man page for a description of all Tdpack error messages and/or
       informational messages.
