Errors
If the function returns < 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.
Error codes from the cc_WaitCall( ) function include the following:
Error Code Description
ERR_ISDN_LIB | E_ISBADPAR Bad input parameter
ERR_ISDN_LIB | E_ISBADTS Bad time slot
ERR_ISDN_LIB | E_ISBADIF Bad interface number
ERR_ISDN_LIB | E_ISBADCRN Bad call reference number
ERR_ISDN_LIB | E_ISNULLPTR Null pointer error
