G__get_list_of_mapsets()

void G__get_list_of_mapsets

(

void

)

Fill list of mapsets from search path (internal use only)

G_add_mapset_to_search_path()

void G_add_mapset_to_search_path

(

const char *

mapset

)

Add mapset to the list of mapsets in search path.

Mapset is add in memory only, not to the SEARCH_PATH file! List is check first if already exists.

Parameters

mapset

mapset name to be added to the search path

G_create_alt_search_path()

void G_create_alt_search_path

(

void

)

Define alternative mapset search path.

G_get_available_mapsets()

char ** G_get_available_mapsets

(

void

)

Get list of available mapsets for current location.

List is updated by each call to this function.

Returns

pointer to NULL terminated array of available mapsets

G_get_mapset_name()

const char * G_get_mapset_name

(

int

n

)

Get name of the n'th mapset from the current mapset search path.

The first call will initialize the list.

Parameters

n	mapset index

Returns

mapset name

NULL if mapset not found

G_is_mapset_in_search_path()

int G_is_mapset_in_search_path

(

const char *

mapset

)

Check if given mapset is in search path.

Parameters

mapset

mapset name

Returns

1 mapset found in search path

0 mapset not found
