You can use Groonga as a library. You need to use the following APIs to initialize and finalize Groonga.
grn_init() initializes Groonga. In contrast, grn_fin() finalizes Groonga.
You must call grn_init() only once before you use APIs which are provided by Groonga. You must call grn_fin() only once after you finish to use APIs which are provided by Groonga.
Here is an example that uses Groonga as a full-text search library.
grn_rc rc;
/* It initializes resources used by Groonga. */
rc = grn_init();
if (rc != GRN_SUCCESS) {
return EXIT_FAILURE;
}
/* Some Groonga API calling codes... */
/* It releases resources used by Groonga. */
grn_fin();
return EXIT_SUCCESS;
grn_init() initializes resources that are used by Groonga. You must call it just once before you call other Groonga APIs.
Returns: | GRN_SUCCESS on success, not GRN_SUCCESS on error. |

grn_fin() releases resources that are used by Groonga. You can't call other Groonga APIs after you call grn_fin().
Returns: | GRN_SUCCESS on success, not GRN_SUCCESS on error. |
