使用posix_timer编程，内存泄露问题
我使用posix_timer创建定时器，
代码如下：

C/C++ code

#include<stdio.h>
#include<time.h>
#include<signal.h>
#include<pthread.h>
#include<stdlib.h>
#include<string.h>
#include<unistd.h>
#include<iostream>
using namespace std;

void fun1(sigval_t   v)
{
    printf("122334\n");
}

timer_t   tid1;

typedef void(*pFun)(sigval_t);

int SetTimer(pFun pfun,timer_t &tid,int seconds,int id)
{
    struct   sigevent   se;
    struct   itimerspec   ts,   ots;
    memset(&se,0,sizeof(sigevent));
    memset(&ts,0,sizeof(itimerspec));
    memset(&ts,0,sizeof(itimerspec));

    se.sigev_notify   =   SIGEV_THREAD;
    se.sigev_notify_function   =   pfun;
    se.sigev_value.sival_int   =   id;

    timer_create(CLOCK_REALTIME,&se,&tid);

    ts.it_value.tv_sec   =   3;
    ts.it_value.tv_nsec   =   0;
    ts.it_interval.tv_sec   =   seconds;
    ts.it_interval.tv_nsec   =   0;
    if(timer_settime(tid,TIMER_ABSTIME,&ts,&ots) < 0)
    {
        return   -1;
    }

    return   0;
}

int main ()
{
    pFun pfun = fun1;
    SetTimer(pfun,tid1,13,1);

    for(int i =0;i<5;i++ )
    {
        printf("11111\n");
        sleep(1);
    }
    timer_delete(tid1);

    return 1;
}

使用valgrind进行内存检测，出现内存泄露情况 
如下：

我哪里使用错误？还是valgrind有问题？请指定，谢谢！


------解决方案--------------------
valgrind 没有用过，看起来未释放的是pthread tls内存。

楼主可以试试建立一个只包含空的main函数的程序，然后用valgrind检查看看。
------解决方案--------------------
问题出现在
SetTimer(void (*)(sigval), void*&, int, int) (main.cpp:38)
main (main.cpp:55)

代码中
SetTimer(pfun,tid1,13,1);
typedef void(*pFun)(sigval_t);
------解决方案--------------------

探讨

to：root_jli

这是函数指针
typedef void(*pFun)(sigval_t);
SetTimer(pfun,tid1,13,1);

如何释放？
