TCAP component IDs are used in the component definitions to represent invoke IDs, linked IDs (ITU-T), and correlation IDs (ANSI).
They consist of a flag to indicate if the ID is present or not (for example, for optional IDs). If the ID is present, an ID value is also specified.
For the present flag, use the present or not present identifiers defined in sccpapi.h.
typedef struct Tcap_CompId
{
U8 present; /* component ID present/not present */
U8 compId; /* component ID value */
U8 fill; /* fill for alignment */
U8 fill2; /* fill for alignment */
} TcapCompId;
