mariadb utf8mb4

To use the utf8mb4 character set with MariaDB in C, you need to ensure that your database connection uses the correct character set. You can do this by executing the "SET NAMES utf8mb4" query after establishing the connection. Here's an example of how you can achieve this:

#include <mysql.h>

int main() {
    MYSQL *conn;

    conn = mysql_init(NULL);

    if (conn == NULL) {
        fprintf(stderr, "Failed to initialize MySQL connection\n");
        return 1;
    }

    if (mysql_real_connect(conn, "localhost", "user", "password", "database", 0, NULL, 0) == NULL) {
        fprintf(stderr, "Failed to connect to database: Error: %s\n", mysql_error(conn));
        mysql_close(conn);
        return 1;
    }

    if (mysql_set_character_set(conn, "utf8mb4") != 0) {
        fprintf(stderr, "Failed to set character set: Error: %s\n", mysql_error(conn));
        mysql_close(conn);
        return 1;
    }

    if (mysql_query(conn, "SET NAMES utf8mb4") != 0) {
        fprintf(stderr, "Failed to set names: Error: %s\n", mysql_error(conn));
        mysql_close(conn);
        return 1;
    }

    // Rest of your code...

    mysql_close(conn);
    return 0;
}

In this example, we first initialize the MySQL connection using mysql_init(). Then, we use mysql_real_connect() to establish a connection to the database. If the connection is successful, we proceed to set the character set to utf8mb4 using mysql_set_character_set(). Finally, we execute the "SET NAMES utf8mb4" query using mysql_query().

Please note that this is just a basic example to demonstrate how to set the character set in a C program using MariaDB. You may need to modify the code according to your specific requirements.

I hope this helps! Let me know if you have any further questions.
