# DESCRIPTION
|
||
|
|
|
||
|
|
Pass a pointer to a long to receive a detailed error code when the most recent
|
||
|
|
transfer returned a **CURLE_PROXY** error. That error code matches the
|
||
|
|
**CURLproxycode** set.
|
||
|
|
|
||
|
|
The error code is zero (**CURLPX_OK**) if no response code was available.
|
||
|
|
|
||
|
|
# PROTOCOLS
