ncl_gagetr - Man Page

CALL GAGETR (PNAM,RVAL)

#include <ncarg/ncargC.h>

void c_gagetr (char *pnam, float *rval)

PNAM

(an input constant or variable of type CHARACTER) is a string three or more characters in length, the first three characters of which constitute the name of the internal parameter whose value is to be retrieved.

RVAL

(an output variable of type  REAL)  is the name of a variable into which the value of the internal parameter specified by PNAM is to be retrieved. If the internal parameter is of type INTEGER and has the value "i", "REAL(i)" will be returned in RVAL.

The C-binding argument descriptions are the same as the FORTRAN  argument descriptions.

This routine allows you to retrieve the current value of Gridall parameters.  For a complete list of parameters available in this utility, see the gridall_params man page.

To use GAGETR or c_gagetr, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.  

See the gridall man page for a description of all Gridall error messages and/or informational messages.
