5.14. GlobalCall API Function Restrictions

R4 for DM3 supports all GlobalCall functions except those noted in Table 12. List of GlobalCall API Functions Restricted and Not Supported. See the GlobalCall API Software Reference for detailed information about each function.

Table 12 lists the GlobalCall functions that are either not supported or are supported with restrictions, indicates if a function is line-related or call-related, and references more information if appropriate.

NOTE:

If you execute a GlobalCall function that is not supported by DM3 boards, an EGC_UNSUPPORTED error is produced, which corresponds to the error message "Function is not Supported".
