Example Use Case: Connecting to a MySQL Server

Here is an example use case that demonstrates how to connect to a MySQL server using MySQL Connector/C:

#include <mysql/mysql.h>

int main() {
    // Initialize the MySQL library
    mysql_library_init(0, NULL, NULL);

    // Create a connection to the MySQL server
    MYSQL *conn = mysql_init(NULL);
    if (!conn) {
        printf("Error initializing connection\n");
        return 1;
    }

    // Connect to the MySQL server
    if (!mysql_real_connect(conn, "localhost", "username", "password", "database", 0, NULL, 0)) {
        printf("Error connecting to MySQL server: %s\n", mysql_error(conn));
        mysql_close(conn);
        return 1;
    }

    // Perform operations on the MySQL server
    mysql_query(conn, "SELECT * FROM table_name");

    // Close the connection to the MySQL server
    mysql_close(conn);

    return 0;
}
