Solution 2

For the MySQL syntax.

To add a new user use CREATE USER Syntax[^]

To grant access to do anything other then be able to login.

Use GRANT Syntax[^]

For the MySQL connector for C, download the connector her http://dev.mysql.com/downloads/connector/c/[^]

Hi,

Here are requests to be executed to insert your special user in response to your request :

SQL

CREATE 'newuser'@'localhost' IDENTIFIED BY 'password';
GRANT INSERT ON database.* TO 'newuser'@'localhost';

Here is the code to manage connection and request execution to database, basic stuff :

#include <mysql.h>
#include <stdio.h>

main() {
MYSQL *conn;
MYSQL_RES *res;
MYSQL_ROW row;

char *server = "localhost";
char *user = "root";
char *password = "PASSWORD"; /* set me first */
char *database = "mysql";

conn = mysql_init(NULL);

/* Connect to database */
if (!mysql_real_connect(conn, server,
user, password, database, 0, NULL, 0)) {
fprintf(stderr, "%s\n", mysql_error(conn));
exit(1);
}

/* send SQL query */
if (mysql_query(conn, "show tables")) {
fprintf(stderr, "%s\n", mysql_error(conn));
exit(1);
}

res = mysql_use_result(conn);

/* output table name */
printf("MySQL Tables in mysql database:\n");
while ((row = mysql_fetch_row(res)) != NULL)
printf("%s \n", row[0]);

/* close connection */
mysql_free_result(res);
mysql_close(conn);
}

Hope this Helps.
