int
addBusinessDaysIfValid(
bdlt::Date* result,
bdlt::Date const& original,
bdlt::Calendar const& calendar,
int numBusinessDays);Load, into the specified result, the date that is the specified numBusinessDays chronologically after the specified original date according to the specified calendar. The resulting date is chronologically before the original date for negative values of numBusinessDays, the chronologically earliest business day that is on or after the original date for 0 == numBusinessDays, and chronologically after the original date for positive values of numBusinessDays. Return 0 on success, and a non-zero value, without modifying *result, if either the original date or the resulting date is not within the valid range of calendar. Note that if 0 != numBusinessDays, then the result of addBusinessDaysIfValid(res, orig, cal, numBusinessDays) is identical to the result of subtractBusinessDaysIfValid(res, orig, cal, -numBusinessDays).
0 on success, non-zero on failure
