The “dst” member is valid only during the Proximity Waypoint Transfer Protocol.
7.5.6. D105_Wpt_Type
Example products: StreetPilot (user waypoints).
typedef struct
{
Semicircle_Type posn; /* position */
Symbol_Type smbl; /* symbol id */
/* char wpt_ident[]; null-terminated string */
} D105_Wpt_Type;
7.5.7. D106_Wpt_Type
Example products: StreetPilot (route waypoints).
typedef struct
{
byte wpt_class; /* class */
byte subclass[13]; /* subclass */
Semicircle_Type posn; /* position */
Symbol_Type smbl; /* symbol id */
/* char wpt_ident[]; null-terminated string */
/* char lnk_ident[]; null-terminated string */
} D106_Wpt_Type;
The enumerated values for the “wpt_class” member of the D106_Wpt_Type are as follows:
Zero:
Non-zero:
indicates a user waypoint (“subclass” is ignored).
indicates a non-user waypoint (“subclass” must be valid).
For non-user waypoints (such as a city in the GPS map database), the GPS will provide a non-zero value in the
“wpt_class” member, and the “subclass” member will contain valid data to further identify the non-user waypoint. If
the Host wishes to transfer this waypoint back to the GPS (as part of a route), the Host must leave the “wpt_class”
and “subclass” members unmodified. For user waypoints, the Host must ensure that the “wpt_class” member is zero,
but the “subclass” member will be ignored and should be set to zero.
The “lnk_ident” member provides a string that indicates the name of the path from the previous waypoint in the
route to this one. For example, “HIGHWAY 101” might be placed in “lnk_ident” to show that the path from the
previous waypoint to this waypoint is along Highway 101. The “lnk_ident” string may be empty (i.e., no characters
other than the null terminator), which indicates that no particular path is specified.
7.5.8. D107_Wpt_Type
Example products: GPS 12CX.
