int G__create_alt_search_path

(

void

)

Define alternative mapset search path.

Returns

0

char* G__mapset_name

(

int

n

)

Get name of the n'th mapset from the mapset_name[] list.

The first call will initialize the list.

Parameters

n	mapset index

Returns

int G__switch_search_path

(

void

)

Switch mapset 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

char** G_available_mapsets

(

void

)

Get list of available mapsets for current location.

List is updated by each call to this function

Returns

pointer to zero terminated array of available mapsets.

mapset

)

Parameters

mapset

mapset name

Returns

1 mapset found in search path

0 mapset not found
