Function Documentation

void G__get_list_of_mapsets ( void  )

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

Definition at line 57 of file mapset_nme.c.

References fclose(), G_fopen_old(), G_mapset(), G_mapset_permissions(), GNAME_MAX, name, and NULL.

Referenced by G_get_mapset_name(), and G_init_all().

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
mapsetmapset name to be added to the search path

Definition at line 195 of file mapset_nme.c.

References G_is_mapset_in_search_path().

void G_create_alt_search_path ( void  )

Define alternative mapset search path.

Definition at line 103 of file mapset_nme.c.

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 zero terminated array of available mapsets

Definition at line 144 of file mapset_nme.c.

References G_debug(), G_location_path(), G_stat(), G_store(), GPATH_MAX, NULL, opendir(), and readdir().

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
nmapset index
Returns
mapset name
NULL if mapset not found

Definition at line 44 of file mapset_nme.c.

References G__get_list_of_mapsets(), and NULL.

int G_is_mapset_in_search_path ( const char *  mapset)

Check if given mapset is in search path.

Parameters
mapsetmapset name
Returns
1 mapset found in search path
0 mapset not found

Definition at line 209 of file mapset_nme.c.

Referenced by G_add_mapset_to_search_path().

void G_reset_mapsets ( void  )

Reset number of mapsets.

Definition at line 132 of file mapset_nme.c.

void G_switch_search_path ( void  )

Switch mapset search path.

Definition at line 114 of file mapset_nme.c.
