Instead, all communication and synchronisation is managed +using System V (XSI) semaphores and System V (XSI) shared memory. +.PP +The command \fBbus create\fP can be used to create new buses. By +convention, buses should be stored in \fI$XDG_RUNTIME_DIR/bus\fP, this is +what \fBbus create\fP does if no pathname is given. The pathname of the +bus should be tracked using \fIBUS_X\fP, where \fIX\fP is replaced with +either: +.TP +.B GENERIC +For the bus used in generic cases. That is all but the cases of the +buses listed below. +.TP +.B AUDIO +For the bus used in with the audio subsystem is involved. +.TP +.B VIDEO +For the bus used in with the video subsystem is involved. +.TP +.B INPUT +For the bus used in with the input subsystem is involved. +.TP +.B FILES +For the bus used in with the storage subsystem is involved. +.PP +Messages broadcasted on a bus cannot be longer than 2047 bytes, +excluding NULL termination. Message should be encoded in UTF-8, +and most not contain the NULL character. +.PP +Broadcasted message should start with the process ID, or 0 if ephemeral, +whence the message originated, followed by a single regular space. +.SH SEE ALSO +.BR bus (1), +.BR libbus (7), +.BR semop (2), +.BR shmop (2) +.SH AUTHORS +Principal author, Mattias Andrée.
