Radare2将文件,网络,debugger这些对象的访问以及其所有的输入输出都包纳于IO抽象层中,并将这些对象作为文件处理。
IO插件用于在虚拟文件系统封装open,read,write和'system'操作,可以令radare将任何东西视为一个平坦文件对象,例如socket连接,远程radare session,文件,进程,设备,gdb session等。
当radare读入字节块时,IO插件起到的作用是从文件中获取字节并将其放置在内置的Buffer里。Radare会根据文件URI选择不同的IO插件去打开文件,例如:
Debugging URIs
$ r2 dbg:///bin/ls<br />
$ r2 pid://1927
Remote sessions
$ r2 rap://:1234<br />
$ r2 rap://<host>:1234//bin/ls
Virtual buffers
$ r2 malloc://512<br />
shortcut for
$ r2 -
使用radare2 -L
