Environment variables

The following environment variables affect the behaviour of libvpb.

VPB_COUNTRY

Sets the region to use for global default values. Its value may be either a string, indicating the name of the region such as AUSTRALIA, JAPAN, UK, USA, or the numerical value of that region used for international phone numbering, such as 61, 81, 44, 1, respective to the names above. If not specified, the default value is AUSTRALIA. Per port country selection may be made programmatically using the vpb_set_country() api call, or through the use of a configuration file.

VPB_TONE

Sets new default parameters for use by the programmable tone detector. The variables VPB_TONE1 ... VPB_TONE9 may also be specified if more than one tone is to be redefined.

VPB_VERBOSE

If set to the value of 1, this variable will cause libvpb to output debugging messages tracing its activity to stdout. If set to any other value it will be used as the path to a file where such messages will be written.

VPB_MODEL

If set to the string "V4LOG", this variable indicates that OpenLog cards should be assumed if the OpenLine card type has not otherwise been explicitly specified. Has no effect with cards of other types.
