MongoDB C Driver

The MongoDB C Driver, also known as “libmongoc”, is the official client library for C applications, and provides a base for MongoDB drivers in higher-level languages.

The library is compatible with all major platforms. It depends on libbson to create and parse BSON data.

See Installing the MongoDB C Driver (libmongoc) and BSON library (libbson).

To connect to a MongoDB Atlas cluster, use the Atlas connection string for your cluster:

#include <mongoc/mongoc.h>
int main (int argc, char *argv[]) {
mongoc_database_t *database;
mongoc_client_t *client;
mongoc_init ();
client = mongoc_client_new(
"mongodb+srv://<username>:<password>@<cluster-url>/test?retryWrites=true&w=majority"
);
database = mongoc_client_get_database (client, "test");
mongoc_database_destroy (database);
mongoc_client_destroy (client);
mongoc_cleanup ();
return 0;
}

See Advanced Connections for more ways to connect.
