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_ReqANI( ) function include the following:
