The external - identifier string may be in any format, may be the empty string, - and has no restrictions on the charset — however, it must - always be <constant>NUL</constant>-terminated. The returned string - will be the concatenation of the bus path prefix plus an escaped - version of the external identifier string. This operation may be - reversed with <function>sd_bus_decode()</function>.

It - takes a bus path and a prefix string, plus a place to store the - returned external identifier string.
