does group exist?
Returns 1 if the specified group exists in the current mapset; 0 otherwise. Use I_find_group2 to search in all or a specific mapset.

Does the group exists?
Finds a group in specified mapset or any mapset if mapset is not set. Internally uses G_find_file2().

const char* I_find_signature | ( | I_SIGFILE_TYPE | type, |
char * | name, | ||
const char * | mapset | ||
) |
Find mapset containing signature file.
Looks for the signature name of type type in the database. The mapset parameter can either be the empty string "", which means search all the mapsets in the users 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 signature only in this one mapset (for example, in the current mapset). If found, the mapset where the signature lives is returned. If not found, the NULL pointer is returned.
Note: If the user specifies a fully qualified signature name which exists, then I_find_signature() modifies name by removing the "@<i>mapset</i>". Use I_find_signature2 if altering passed in name is not desired.

Note: The passed name argument is not altered. Use I_find_signature if stripping mapset part from the name is desired.
