Definition in file get_window.c.
void G_get_default_window | ( | struct Cell_head * | window | ) |
Get the default region.
Reads the default region for the location into region. 3D values are set to defaults if not available in WIND file.
An error message is printed and exit() is called if there is a problem reading the default region.
[out] | window | pointer to Cell_head |

const char * | name, | ||

Get region for selected element (raster, vector, window, etc.)
G_fatal_error() is called on error

void G_get_window | ( | struct Cell_head * | window | ) |
Get the current region.
Reads the region as stored in the WIND file in the user's current mapset into region.
3D values are set to defaults if not available in WIND file. An error message is printed and exit() is called if there is a problem reading the region.
Note: GRASS applications that read or write raster maps should not use this routine since its use implies that the active module region will not be used. Programs that read or write raster map data (or vector data) can query the active module region using Rast_window_rows() and Rast_window_cols().
