1.4 signal-based resolver timeouts
1.5 get rid of PATH_MAX
1.6 Modified buffer size approach
- 1.7 Detect when called from within callbacks
1.8 CURLOPT_RESOLVE for any port number
1.9 Cache negative name resolves
1.10 auto-detect proxy
Dynamically allocate buffer size depending on protocol in use in combination
with freeing it after each individual transfer? Other suggestions?
-1.7 Detect when called from within callbacks
-
- We should set a state variable before calling callbacks, so that we
- subsequently can add code within libcurl that returns error if called within
- callbacks for when that's not supported.
-
1.8 CURLOPT_RESOLVE for any port number
This option allows applications to set a replacement IP address for a given
Status returned failure when asked with \fICURLOPT_SSL_VERIFYSTATUS(3)\fP.
.IP "CURLE_HTTP2_STREAM (92)"
Stream error in the HTTP/2 framing layer.
+.IP "CURLE_RECURSIVE_API_CALL (93)"
+An API function was called from inside a callback.
.IP "CURLE_OBSOLETE*"
These error codes will never be returned. They were used in an old libcurl
version and are currently unused.
.IP "CURLM_ADDED_ALREADY (7)"
An easy handle already added to a multi handle was attempted to get added a
second time. (Added in 7.32.1)
+.IP "CURLM_RECURSIVE_API_CALL (8)"
+An API function was called from inside a callback.
.SH "CURLSHcode"
The "share" interface will return a CURLSHcode to indicate when an error has
occurred. Also consider \fIcurl_share_strerror(3)\fP.
