Getting pid of exec'd process

Hi,

Can anyone suggest as to how can I get the pid of the process which I have done execv()?
ie, if I do execv(path, cmd) a new process will be launched and now how can I get the pid of this new process?

Regard
Prasanta

Hi,

If you are doing execv after creating a child process using fork, then return value of fork will give you the pid of the process.

If you haven't done any fork, then the pid is same the calling process (execv doesn't create any new process, it overwrites the process image of calling one) and can be obtained using the getpid() system call.

hello Prasanta, maybe you can look at
http://patatra.mine.nu/cash/cash.tar.gz

it contains a shell of 160 line of code that uses fork() and execvp() maybe the source code can help you to learn.
Hope this helps.
