AGGETR(3NCARG)

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

SYNOPSIS
CALL AGGETR (TPGN,FUSR)

C-BINDING SYNOPSIS
#include <ncarg/ncargC.h>

void c_aggetr (char *tpgn, float *fusr)

DESCRIPTION

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.

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 Autograph parameters. For a complete list of parameters available in this utility, see the autograph_params man page.

ACCESS
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.
