栈桢（stack frame）
有函数A 。 当此函数出栈时会出现栈破碎。 十分郁闷 函数有如下语句 [quote]char temp[16]; memcpy(temp, bp, len); temp[len]='\0'; fprintf(stdout, "sport char %s\n", temp);[/quote] 上面的正常 可以按字符串形势打印出端口。 [quote]info->sourceport=atoi(temp); fprintf(stdout, "sport=%d\n", info->sourceport);[/quote] info->sourceport是个UINT32型。 上...

现今，见到的比较多的ethernet frames有如下的四种： a. Ethernet II b. Ethernet 802.3 (Raw), aka Novell Ethernet c. Ethernet 802.3/802.2 by IEEE d.

Inverse Arp Request When encapsulating other protocols the data field of the frame Relay packet contains a Network Level Protocol Identification (NLPID) which can be 0xCC (IP), 0x80 (Sub-Network Access Protocol - SNAP) or 0x81 (OSI). When a SNAP header is identified, the 3-byte Organisational Unique Identifier (OUI) and the 2-byte Protocol Identifier (PID) further identifies the protocol. ...
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...
