Description:
mysql_send_long_data doesn't work in embedded mysql. mysql_stmt_error reports no error, 
mysql_error reports wrong arguments for get_longdata. 
 
 

How to repeat:
#include <mysql.h> 
#include <stdio.h> 
 
 
int main() { 
	int		rc; 
	MYSQL 		*mysql; 
	MYSQL_BIND	bind[2];	 
	MYSQL_STMT	*stmt; 
	MYSQL_RES	*res; 
	MYSQL_ROW	row; 
	char		str1[100]; 
 
#ifdef EMBEDDED 
	mysql_server_init(0, NULL, NULL); 
#endif 
 
	mysql = mysql_init(NULL); 
#ifdef EMBEDDED 
	if (mysql_real_connect(mysql, NULL, NULL, NULL, "", 0, NULL, 0) == NULL) { 
#else 
	if (mysql_real_connect(mysql, "localhost", "root", "", "", 0, NULL, 0) == NULL) { 
#endif 
		printf("error\n"); 
	} 
 
 
	mysql_select_db(mysql, "test"); 
 
	mysql_query(mysql, "DROP TABLE testld"); 
 
	mysql_query(mysql,"CREATE TABLE testld(a int, b long varbinary)"); 
 
	stmt = mysql_prepare(mysql, "INSERT INTO testld (a, b) VALUES (1,?)", 100); 
 
	bind[0].buffer_type=FIELD_TYPE_STRING; 
	bind[0].is_null=0; 
	bind[0].buffer_length=0;		 
	bind[0].length=0;				 
 
	mysql_bind_param(stmt,bind); 
 
  	strcpy(str1, "This is a simple test"); 
	mysql_send_long_data(stmt,0,str1,strlen(str1)); 
 
	if (mysql_stmt_errno(stmt)) { 
		printf ("Error: %s\n", mysql_stmt_error(stmt)); 
	} 
 
	mysql_execute(stmt); 
 
	mysql_stmt_close(stmt); 
 
	mysql_query(mysql, "SELECT * FROM testld"); 
	res = mysql_store_result(mysql); 
	row = mysql_fetch_row(res); 
	printf ("A: %s B: %s\n", row[0], row[1]); 
	mysql_free_result(res); 
 
	mysql_close(mysql); 
#ifdef EMBEDDED 
	mysql_server_end(); 
#endif 
}
