Function Documentation

◆ G__mapset()

const char * G__mapset ( void  )

Get current mapset name (internal use only)

See G_mapset().

NULL on error

◆ G__mapset_path()

char * G__mapset_path ( void  )

Get current mapset UNIX-like path (internal use only)

Allocated buffer should be freed by G_free(). See also G_mapset_path().

Support also Windows-like path (?)

◆ G_mapset()

const char * G_mapset ( void  )

Get current mapset name.

Returns the name of the current mapset in the current location. This routine is often used when accessing files in the current mapset. See Mapsets for an explanation of mapsets.

G_fatal_error() is called on error.

◆ G_mapset_path()

char * G_mapset_path ( void  )

Get current mapset UNIX-like path.

Allocated buffer should be freed by G_free(). See G__mapset_path().

Returns the full UNIX path name of the current mapset. For example, if the user is working in mapset user1, location spearfish in the /home/user/grassdata database directory, this routine will return a string which looks like /home/user/grassdata/spearfish/user1.

This function also checks if mapset path is readable by the current user. It calls G_fatal_error() on failure.
