need_compatibility_before()

static bool need_compatibility_before ( const struct options *  o, unsigned int  version  )

The option –compat-mode is used to set up default settings to values used on the specified openvpn version and earlier.

This function is used in various "default option" paths to test if the user requested compatibility with a version before the one specified as argument. This way some default settings can be automatically altered to guarantee compatibility with the version specified by the user via –compat-mode.

Parameters

version

need compatibility with openvpn versions before the one specified (20401 = before 2.4.1)

Returns

whether compatibility should be enabled
