The pipe interface can be disabled +by the program which initialises the library. pigpiod offers +the -f option to disable the pipe interface. User programs +should call <a href= +"http://abyz.me.uk/rpi/pigpio/cif.html#gpioCfgInterfaces">gpioCfgInterfaces</a> +if they wish to disable the pipe interface.<br> +<br> +pigpio listens for commands on pipe /dev/pigpio. The commands +consist of a command identifier with, depending on the command, +zero, one, or two parameters. The result, if any, may be read +from pipe /dev/pigout.
