TDGETR(3NCARG) NCAR GRAPHICS TDGETR(3NCARG)

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.
