NAME¶
ARGETR - Retrieves the real value of an Areas parameter.
SYNOPSIS¶
CALL ARGETR (PNAM,RVAL)
C-BINDING SYNOPSIS¶
#include <ncarg/ncargC.h>
void c_argetr (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 Areas parameters. For a complete list of parameters available in this utility, see the areas_params man page.
ACCESS¶
To use ARGETR or c_argetr, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
MESSAGES¶
See the areas man page for a description of all Areas error messages and/or informational messages.
