You're calling mysql_free_result() on a pointer that has never
been used or initialized. That is, why call mysql_free_result()
when you've never called mysql_store_result()?

Subject: Why the error here?
Hello,
I am trying to use:
mysql_create_db in a C program. It compiles and links OK. But when you
execute the program, I get the following error.
#include "mysql.h"
#include "mysql.h"
#include <stdio.h>
#include <stdlib.h>
MYSQL mysql;
MYSQL_RES *res;
MYSQL_ROW row;
char *db = "db";
void exiterr(int exitcode)
{
fprintf( stderr, "%s\n", mysql_error(&mysql) ); exit( exitcode );
}
main()
{
char db;
printf("Enter a name for your new database\n\n"); scanf("%s", &db);
if (!(mysql_connect(&mysql,"localhost","root",""))) exiterr(1);
if (mysql_create_db(&mysql, &db))
exiterr(2);
mysql_free_result(res);
mysql_close(&mysql);
}
When I run my code here is what I get:
[root@oscar mysql_c]# ./connect
Enter a name for your new database
homes
Segmentation fault
BUT.... The database is added to mysql. I can connect to it, and view the
"empty set". Why the segmentation fault???
Thank you in andvance.
