Function Documentation

◆ G__mapset()

const char* G__mapset ( void  )

Get current mapset name (internal use only)

See G_mapset().

Returns
pointer mapset name
NULL on error

Definition at line 51 of file gis/mapset.c.

References G_getenv_nofatal().

Referenced by G__mapset_path(), and G_mapset().

◆ 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().

Todo:
Support also Windows-like path (?)
Returns
buffer with mapset path

Definition at line 96 of file gis/mapset.c.

◆ G_mapset()

◆ 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.

Returns
buffer with location path
