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.
