interposing library calls - here is another one Here is another purpose I have for wanting to try library interposing. There already exists an interposing "kit" (I wouldn't call it an application) to intercept socket connections and drive them through a specified SOCKS server instead of making the connection directly. What I want to do is a variation on that ... 9 Jul 2008 15:46

Questions about getopt() (Linux) 1) Is it documented anywhere that you have to reset optind to 0 in order to use getopt again (i.e., to use it more than once in a single program) ? Observation: I've discovered this on my own at least twice now, the hard way. 2) Is it documented anywhere how/that getopt silently ignores the 0 element of the passe... 18 Jul 2008 10:17

interposing library calls - here is one I want to do I know some people have been wondering what I wanted to do with library interposing. There actually are several different things. Ideas have collected over many years, and this has gradually reached a threshold where I want to actually start doing this, and maybe set up a general framework for it. But for this p... 11 Jul 2008 01:45
using socket fd to another pid (?) Folks, If you have a process identifier (PID) which creates a socket, connects and performs network I/O (e.g. read, write,etc), is it possible for that pid to pass the socket file descriptor to a second pid, such that the second pid can perform read, write operations? For example if you had theoretically multipl... 9 Jul 2008 18:52 |
