NAME

unix::/dev/null — Redirects a channel to /dev/null.

synopsis

wyrm::unix::/dev/null redirected-channel

description

Close a channel descriptor and reopen it to /dev/null.

caveats

This command plays with file handles behind Tcl's back. Bufferring and other Tcl services can break and be broken by this. dup is intended more to rearrange files, with the channel names standing in for the file descriptors, prior to an exec rather than to duplicate channels within a process itself.
