NAME

       GAGETR - Retrieves the real value of an internal parameter of Gridall.

SYNOPSIS

       CALL GAGETR (PNAM,RVAL)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_gagetr (char *pnam, float *rval)

DESCRIPTION

       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.

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

ACCESS

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

MESSAGES

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