一，Where storage lives It's useful to visualize some aspects of how things are laid out while the program is running, in particular how memory is arranged. There are six different places to store data: Registers. This is the fastest storage because it exists in a place different from that of other storage...

是在vxworks的bsp阶段，bsp不能malloc大空间，查看config.h文件 #undef stack_SAVE #define stack_SAVE 512 /* maximum stack used to preserve */ 不知道同这个512有没有关系？没有板子，暂没办法测。所问一下

Note: I only searched for C/C++ stacks and applications. There also exist a lot of stacks and applications for other programming languages, especially for java. If you are looking for Java stacks/applications, please ask Google. If you have any comments or interesting links, or do you want to report broken links, please contact me RTP stacks (mainly open source C/C++ stacks) jrtplib: C++; Licen...

同样的数据，为什么第一次（无序）使用快排（递归）很正常 而接着再快排，就会stack Overflow呢？ 数据为一个6w多记录的数组，保存一个单链表的节点指针 数组和单链表都在堆上 同样的快排代码 对于int a[63537] = {1, 2, 3, 4, 5, ..., 63537}这样的数据 进行排序，为什么不论排几次都不会Statck Overflow？ :evil: 实在受不了了，高手帮一把，快排的代码没有问题。 ps:每趟快排以第一个数据为基准

程序关于添加/删除路径名的： pushd () { dirname=$1 DIR_stack="$dirname ${DIR_stack:-$PWD' '}" cd ${dirname:?"missing directory name."} echo "$DIR_stack" } POPD () { DIR_stack=${DIR_stack#* } cd ${DIR_stack%% *} echo "$PWD" } pushd lizard 运行后结果为什么是 lizard /root/programmes' ' 预期结果应该是：/root/protrammes lizard 阿。。 程序第4行改成：DIR_stack="${DIR_stack:-$PWD'...

SecurityFocus interviews three OpenBSD developers about their network stack protection against DoS ICMP attacks, a short comparison with Linux' stack, and some thoughts on OpenBGPD. On November 1st, OpenBSD 3.8 will be released. This is the first release that includes protections against some old and simple DoS attacks via ICMP. How do these protections work? Fernando Gont: First of all, I'd lik...

用户查询过程中sybase日志报错，说stack size太小了，但是如何调整呢，调整的单位如何计算，看了一些文档，但是不是十分清楚，有人知道么？

ulimit -a core file size (blocks) unlimited data seg size (kbytes) unlimited file size (blocks) unlimited open files 1024 pipe size (512 bytes) 10 stack size (kbytes) 8192 cpu time (seconds) unlimited max user processes 29995 virtual memory (kbytes) unlimited 我想永久性的修改stack size 的大小，我修改的是/etc/system set rpcmod...

感觉这篇文章讲得不错，贴出来共享 -------------------------------------------------------------------------------- Buffer overflows in user input dependent buffers have become one of the biggest security hazards on the internet and to modern computing in general. This is because such an error can easily be made at programming level, and while invisible for the user who does not understand or cann...
