Errors
If the function returns a value < 0 to indicate failure, use the cc_CauseValue( )
function to retrieve the reason code for the failure. The cc_ResultMsg( ) function
can be used to interpret the reason code. Error codes are defined in the files
ccerr.h, isdnerr.h, and isdncmd.h.
Possible error codes from the cc_RetrieveRej( ) function include the following:
Error Code Description
ERR_ISDN_FW | ISDN_BADSTATE Cannot accept event in current state.
ERR_ISDN_LIB | E_ISNULL_PTR Null pointer error
