双向转发检测BFD（Bidirectional Forwarding Detection）是一种全网统一的检测机制，用于快速检测、 监控网络中链路或者IP路由的转发连通状况。此处列举了BFD与静态路由联动配置，以及BFD与ospf联动配置。 实验拓扑图 一、BFD与静态路由联动配置 （1）ip地址的配置 R1: sys sysn R1 inter g0/0/1 ip address 10.0.13.1 24 inter g0/0/0 ip address 10.0.12.1 24 quit R2: sys sysn R2 inter g0/0/0 ip address 10.0.13.13 24 quit R3： sys sysn R3 inter g0/0/0 ip address 10.0.12.12 24 quit （2）在R2和R3上配置静态路由实现通信 R2: ip route-static 10.0.12.0 24 10.0.13.1 R3: ip route-static 10.0.13.0 24 10.0.12.1 （3）在R1和R2路径上启用BFD配置，检测R1到R2接口 R1: [R1]bfd //启用BFD配置 [R1-bfd]quit [R1]bfd 1 bind peer-ip 10.0.13.13 source-ip 10.0.13.1 auto /

Is it possible to know a function arguments and variables' name types at runtime in C program ? For example, if I have a function: int abc(int x, float y , somestruct z ){ char a; int b ; } Can I know inside this function abc() , what are the names of arguments and variables i.e. in this case its x , y , z , a , b and they are of type int , float , somestruct , char , int . Say if there is another function: float some_func(specialstruct my_struct, int index){ } I should know that arguments name are my_struct , index and types are specialstruct , int . I need this info at runtime ? I have

I tried to compile a 7.x Version of gdb without any luck. I codesigned the executable(http://sourceware.org/gdb/wiki/BuildingOnDarwin). With following version there were these problems. 7.5,7.4,git clone: unknown load command 0x2a (and others) for my application and different system libraries when starting gbd. When trying to print a vector for example i always get: Could not find the frame base for "main(int, char**)" 7.3 (macports and from gdb-website): on starting the application it fails to set the breakpoint and continues to run. (gdb) start Temporary breakpoint 1 at 0x100000950: file ..
