Is Linux, The problem is that the reserved memory is growing in every new thread that is opened and is not liberated.

This simple sample.. have a memory leak.. why???

Why does reserved memory grow stillafter having liberated the threads?? .. should not it be able only like before having created them?

My problem is...

I see the memory usage
Before create threads... and after detach all threads in the
"while(true)
{}" is runnig...in this point the memory will be free

There are only one attr pointer... and...

I have this code...

#include <stdio.h>

Hi, i have an app that uses MYSQL API C.. i trying do a timeout until the table is locked by an other thread , in the docs of Mysql i can see that MYSQL_OPT_READ_TIMEOUT is...

the same results....
You can try to execute the code??...
If you do it, you will be able to see as the virtual memory(report) it is reserved and is not liberated when they finish all the threads

yes, detach is inside client procedure..

static void* cliente(void *datos)
{
int id=pthread_self();
char *buff=(char *)malloc(100000);
sleep(15);
free(buff);
...

Yes, i try to put pthread_detach(pthread_self()); before the call pthread_exit() but the result is the same... allways the virtual memory is over 200 Mb.... only is liberated aprox 30 Mb.

yes this is correct.. but i was waiting that using free before calling to pthread_exit all allocated memory was liberated, and is liberated aprox 30 Mb. (allocated by malloc) but not the rest. !?

Hi, i have this code... in order to test my problem...

#include <stdio.h>
#include <iostream>
#include <pthread.h>
static void* cliente(void *datos);

int main()
{
