由于进程很多，pthread_create的错误返回代码是 35 错误，我用过pthread_exit应该杀死线程不是吗？

我在pthread_create中创建了一个pthread_create，我使用了套接字编程，在那里我接收一个数据包，然后创建一个线程来写文件。当我发送一个非常大的文件，我得到这个错误…??

代码如下:

void *writePack(void *sock)
{
    size_t nbyte;
    ssize_t writeSize;
    nbyte = 1466;
    off_t offset;
    offset = (((struct writePacket *)sock)->seq * 1466);
    char* buffer = new char();
    buffer = ((struct writePacket *)sock)->datamsg;
    writeSize = pwrite(((struct writePacket *)sock)->pp,(const void *)buffer, nbyte, offset );
    free(buffer);
    pthread_exit(NULL);
}

这是父接收代码的代码…

recvfrom(sockA->sockid, (void *)&recvdata, sizeof(struct data), 0, (struct sockaddr *) &cli_addr, &clilen);
        if (n<0)
            error("Error on reading");
        pthread_mutex_lock(&qlock);
                struct writePacket* a;
        a=new writePacket;
        a->sockID = sockA->sockid;
        a->pp = sockA->pp;
        a->seq = recvdata.seq;
        memcpy(a->datamsg,recvdata.datamsg,1466);
        pc = pthread_create(&write[counter], NULL, writePack,(void *) a);
                     if (pc)
                        {
                           printf("ERROR; return code from pthread_create() is %dn", pc);
                             exit(-1);
                        }
