Find a raster map.
Looks for the raster map name in the database. The mapset parameter can either be the empty string "", which means search all the mapsets in the user's current mapset search path (see Mapset_Search_Path for more details about the search path) or it can be a specific mapset name, which means look for the raster map only in this one mapset (for example, in the current mapset). If found, the mapset where the raster map lives is returned. If not found, the NULL pointer is returned.
Note: If the user specifies a fully qualified raster map which exists, then G_find_raster() modifies name by removing the "@<i>mapset</i>".
For example, to find a raster map anywhere in the database:
To check that the raster map exists in the current mapset:
[in,out] | name | map name |
mapset | mapset name or "" |

Find a raster map (look but don't touch)
The same as G_find_raster() but doesn't remove the "@<i>mapset</i>" qualification from name, if present.
Returns NULL if the map wasn't found, or the mapset the raster was found in if it was.

mapset | mapset name or "" |
