in thread question about running a system and a perl function background

Hello,

Is  system 1, supposed to return the child's pid? It seems to return -1 when I tested it out. Is there any other windows command that might return the child's pid?

Thanks for the response.

    The "piped open" (See perlopentut) returns the pid of the child process.

    See also Re^5: question about running a system and a perl function background in this thread for an example of use.

    I believe it should. Have you tried printing "$!" and/or "$^E"? They may give you a meaning the cause of the error.
