Can anyone explain what exactly this routine does? When trying to write an object to display a bitmap or jpeg on the PD canvas I came across this very useful routine. I guess it’s a routine that interpreters tcl/tk scripts? Can anyone explain what exactly is does and what the parameters are? Cheers,

Pd is a client-server system connected by a socket. the client sends to the server using the "pd" proc in Tcl, in the same format as [netsend]. The server sends to the client Tcl commands using sys_gui(), and the client calls "eval" on them.

sys_gui() takes a single string argument. sys_vgui() is a combination of sprintf() with sys_gui(), so it takes the same arguments as printf(), which are (const char *format, ...) where format is a %-string.
