.SH NAME
TDGETR - Retrieves the real value of a Tdpack parameter.
.SH SYNOPSIS
CALL TDGETR (PNAM,RVAL)
.SH C-BINDING SYNOPSIS
#include <ncarg/ncargC.h>
.sp
void c_tdgetr (char *pnam, float *rval)
.SH DESCRIPTION 
The arguments of TDGETR are as follows:
.IP "PNAM" 8
(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.
.IP "RVAL" 8
(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)".
.SH C-BINDING DESCRIPTION 
The C-binding argument descriptions are the same as the FORTRAN 
argument descriptions.
.SH 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.
.SH ACCESS
To use TDGETR or c_tdgetr, load the NCAR Graphics libraries ncarg, ncarg_gks,
and ncarg_c, preferably in that order. 
.SH MESSAGES
See the "tdpack" man page for a description of all Tdpack error
messages and/or informational messages.
