options_string_compat_lzo()

const char* options_string_compat_lzo	(	const char *	options,
		struct gc_arena *	gc
	)

Takes a locally produced OCC string for TLS server mode and modifies as if the option comp-lzo was enabled.

This is to send a client in comp-lzo migrate mode the expected OCC string.

Note: This function expects the string to be in the locally generated format and does not accept arbitrary strings.

Parameters

options	the locally generated OCC string
gc	gc_arena to allocate the returned string in

Returns
