ncl_idgetr: Retrieves the real value of a Bivar parameter.
NAME
IDGETR - Retrieves the real value of a Bivar parameter.
SYNOPSIS
CALL IDGETR (PNAM,RVAL)C-BINDING SYNOPSIS
#include <ncarg/ncargC.h>void c_idgetr (char *pnam, float *rval)
DESCRIPTION
- 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 two 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 Bivar parameters. For a complete list of parameters available in this utility, see the bivar_params man page.ACCESS
To use IDGETR or c_idgetr, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.MESSAGES
See the bivar man page for a description of all Bivar error messages and/or informational messages.COPYRIGHT
