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.

Typically, a < 0 return code for the cc_SetUsrAttr( ) function indicates that the

function reference (the device handle) is not valid for the function call.
