This option requires that libcurl was built with a resolver backend that
|
|
supports this operation. The c\-ares backend is the only such one.
|
|
|
|
Added in 7.24.0
|
|
.SH RETURN VALUE

|
|
CURLE_NOT_BUILT_IN if support was disabled at compile\-time,
|
|
CURLE_BAD_FUNCTION_ARGUMENT when given an invalid server list, or
|
|
CURLE_OUT_OF_MEMORY if there was insufficient heap space.
