in thread Problem with 'system' function in Windows Vista

Hi Joost,


I keep forgetting what system(1, @command) does. (it's windows specific, right?)
Is Windows specific, it is meant to give a non-blocking system call - it gets the result of the creation of the child process and returns it. I have also tried it without the 1, works as expected and gives the same error.

[oiskuu]: ... getlogin refers to tty owner; if you close STDIN, then getlogin returns undef. I get undef in my shell (running under X)
[tye]: Then there is a more persistent big of data similar to getlogin(). I don't believe even daemonizing drops it. So you can tell services that were started at boot time from those started by a person.
[tye]: I'll have to look into that later. getlogin() suites my current needs.
