Agreed, I am not calling mysql_store_result(). I attempted to add
my_free() but the function does not seem to exist, it is also not listed
in the API docs for the c api. As such it still seems that there should
be no leak, but yet I do get one. Thanks for the idea anyway Chris,
maybe you can cla
Hey wait a minute. Where did you get the my_free(), may be you are
trying to say mysql_free(), but then that is used only if result set is
used/called.
But the code does not show any result set call. ie. mysql_use_result()
or mysql_store_result().
So, the question now, how come there is a leak
Hi!
You're looking for the function my_free(). Enjoy!

Chris

Hello,
I am using the mysqlclient library 4.0.14 on win2k.
It works fine but there are memory leaks I have no solutions for.
I have tried this:
int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])
{
MYSQL MySQL;

dmalloc identifies memory leaks when using mysqlclient c library once a malloc and

as dl-open.c and dl-versio

What you *may* be seeing is standard memory fragmentation that many

Hi !
I've made a quite simple program in C using
libmysqlclient. The program runs as daemon
in Solaris 8 (sparc) and checks some values
in the database every 5 minutes.
I have only ONE malloc/realloc call in "my" code
and this code is called only when needed (when DB check
is signaling it to do

HI,
Firstly I hope this is the right list as the enquiry I have I do not class
as a bug due to my uncertainty about where the problem lies.
I have been using the C API for MySQL 2.22.32 on Linux 2.2.14 and I have
noticed that my program was getting to an unmanageable size in memory, there
is a s
test.c -o test -lmysqlclient -g
At the software creating, it's worth using (at least for tests)
functions from header . It's very usefull for finding memory
leaks. Now, take a look at second example:
- test2.c
#include
#include
