Function Documentation

int G_get_cellhd ( const char *  name,
const char *  mapset,
struct Cell_head *  cellhd 

Read the raster header.

The raster header for the raster map name in the specified mapset is read into the cellhd structure. If there is an error reading the raster header file, a diagnostic message is printed and -1 is returned. Otherwise, 0 is returned.

Note:a warning message for errors encountered.

Cell header files may contain either grid cell header information or reclass information. If it is a reclass file, it will specify the map and mapset names of the actual grid cell file being reclassed. G_get_cellhd(), upon reading reclass information will go read the cell header information for the referenced file. Only one reference is allowed.
