Function Documentation
◆ G__get_list_of_mapsets()
| 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.
Referenced by G_get_mapset_name(), and G_init_all().
◆ 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
Definition at line 200 of file mapset_nme.c.
References G_is_mapset_in_search_path().
◆ G_create_alt_search_path()
| void G_create_alt_search_path | ( | void | ) |
Define alternative mapset search path.
Definition at line 103 of file mapset_nme.c.
◆ 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

References G_calloc, G_debug(), G_free(), G_location_path(), G_realloc, G_stat(), G_store(), GPATH_MAX, NULL, opendir(), and readdir().
◆ 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

References G__get_list_of_mapsets(), and NULL.
◆ 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

◆ G_reset_mapsets()
| void G_reset_mapsets | ( | void | ) |
Reset number of mapsets.
Definition at line 132 of file mapset_nme.c.
◆ G_switch_search_path()
| void G_switch_search_path | ( | void | ) |
