File:Stdstreams-notitle.svg

[edit] Summary

I made this simple diagram of Unix and C standard streams (stdio) using Graphviz. Depicted: a text terminal, the running program, the streams standard input stdin, standard output stdout, standard error stderr. Commandline was

<stdstreams.dot dot -Tsvg >stdstreams.svg

Because of a Commons bug I needed to edit the svg file in text editor to remove title tags before the upload succeeded.
