Hi,
I don't use C APPI, but found this in docs for you :
*********** connect sample :
MYSQL mysql;
mysql_init(&mysql);
mysql_options(&mysql,MYSQL_READ_DEFAULT_GROUP,"your_prog_name");
if (!mysql_real_connect(&mysql,"host","user","passwd","database",0,NULL,0))
{
fprintf(stderr, "Failed to connect to database: Error: %s\n",
mysql_error(&mysql));
}
********************
They give port, unix_socket, client_flag the values 0,NULL,0. Try this.
All the rest is at http://dev.mysql.com/doc/mysql/en/mysql-real-connect.html
and http://dev.mysql.com/doc/mysql/en/c-api-functions.html
