Description

The function map-processes calls function on processes.

function is passed each live process (as determined by process-alive-p) in turn as its single argument.

For a process argument p , if function returns nil then map-processes continues by calling function on another process, but if function returns true then map-processes returns p immediately and stops calling function (so function may not get called on all processes).
