NAME¶
MAPGTR - Gets the current value of a specified EZMAP parameter of type REAL.
MPGETR is an alternate name for the routine MAPGTR.
SYNOPSIS¶
CALL MAPGTR (PNAM,RVAL)
C-BINDING SYNOPSIS¶
#include <ncarg/ncargC.h>
void c_mapgtr (char *pnam, float *rval)
DESCRIPTION¶
- PNAM
- (an input expression of type CHARACTER) specifies the name of the
parameter to get. Only the first two characters of the string are
examined.
- RVAL
- (an output variable of type REAL) receives the value of the parameter
specified by PNAM.
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 EZMAP parameters. For a
complete list of parameters available in this utility, see the ezmap_params
man page.
EXAMPLES¶
Use the ncargex command to see the following relevant example: mpex07.
ACCESS¶
To use MAPGTR, MAPGETR, or c_mapgtr load the NCAR Graphics libraries ncarg,
ncarg_gks, and ncarg_c, preferably in that order.
MESSAGES¶
See the ezmap man page for a description of all EZMAP error messages and/or
informational messages.
