If no push callback is set, all offered +pushes will be denied automatically. +.SH CALLBACK DESCRIPTION +The callback gets its arguments like this: + +\fIeasy\fP is a newly created handle that represents this new transfer. + +\fIparent\fP is the handle of the stream on which this push arrives. The new +handle has been duphandle()d from the parent, meaning that it has gotten all +its options inherited. It is then up to the application to alter any options +if desired. + +\fInum_headers\fP is the number of name+value pairs that was received and can +be accessed + +\fIheaders\fP is a handle used to access push headers using the accessor +functions described below. This only accesses and provides the PUSH_PROMISE +headers, the normal response headers will be provided in the header callback +as usual. + +\fIuserp\fP is the pointer set with \fICURLMOPT_PUSHDATA(3)\fP + +If the callback returns CURL_PUSH_OK, the 'easy' handle will be added to the +multi handle, the callback must not do that by itself. + +The callback can access PUSH_PROMISE headers with two accessor +functions. These functions can only be used from within this callback and they +can only access the PUSH_PROMISE headers. The normal response headers will be +pased to the header callback for pushed streams just as for normal streams. +.IP curl_pushheader_bynum +Returns the header pair at index 'num' (or NULL). The returned pointer points +to a struct that will be freed when this callback returns. +.IP curl_pushheader_byname +Returns the header pair for the given header name (or NULL). This is a +shortcut so that the application doesn't have to loop through all headers to +find the one it is interested in. +.SH CALLBACK RETURN VALUE +.IP "CURL_PUSH_OK (0)" +The application has accepted the stream and it can now start receiving data, +the ownership of the CURL handle has been taken over by the application. +.IP "CURL_PUSH_DENY (1)" +The callback denies the stream and no data for this will reach the +application, the easy handle will be destroyed by libcurl. +.IP * +All other return codes are reserved for future use. +.SH DEFAULT +NULL, no callback +.SH PROTOCOLS +HTTP(S) (HTTP/2 only) +.SH EXAMPLE +TODO +.SH AVAILABILITY +Added in 7.44.0 +.SH RETURN VALUE +Returns CURLM_OK if the option is supported, and CURLM_UNKNOWN_OPTION if not. +.SH "SEE ALSO" +.BR CURLMOPT_PUSHDATA "(3), " CURLMOPT_PIPELINING "(3), " CURLOPT_PIPEWAIT "(3), " +.BR RFC 7540 diff --git a/docs/libcurl/opts/Makefile.am b/docs/libcurl/opts/Makefile.am index 5517811d0..4865b41b5 100644 --- a/docs/libcurl/opts/Makefile.am +++ b/docs/libcurl/opts/Makefile.am @@ -114,7 +114,8 @@ man_MANS = CURLOPT_ACCEPT_ENCODING.3 CURLOPT_ACCEPTTIMEOUT_MS.3 \ CURLMOPT_SOCKETDATA.3 CURLMOPT_SOCKETFUNCTION.3 CURLMOPT_TIMERDATA.3 \ CURLMOPT_TIMERFUNCTION.3 CURLOPT_UNIX_SOCKET_PATH.3 \ CURLOPT_PATH_AS_IS.3 CURLOPT_PROXY_SERVICE_NAME.3 \ - CURLOPT_SERVICE_NAME.3 CURLOPT_PIPEWAIT.3 + CURLOPT_SERVICE_NAME.3 CURLOPT_PIPEWAIT.3 CURLMOPT_PUSHDATA.3 \ + CURLMOPT_PUSHFUNCTION.3 HTMLPAGES = CURLOPT_ACCEPT_ENCODING.html CURLOPT_ACCEPTTIMEOUT_MS.html \ CURLOPT_ADDRESS_SCOPE.html CURLOPT_APPEND.html \ @@ -222,7 +223,8 @@ HTMLPAGES = CURLOPT_ACCEPT_ENCODING.html CURLOPT_ACCEPTTIMEOUT_MS.html \ CURLMOPT_TIMERDATA.html CURLMOPT_TIMERFUNCTION.html \ CURLOPT_UNIX_SOCKET_PATH.html CURLOPT_PATH_AS_IS.html \ CURLOPT_PROXY_SERVICE_NAME.html CURLOPT_SERVICE_NAME.html \ - CURLOPT_PIPEWAIT.html + CURLOPT_PIPEWAIT.html CURLMOPT_PUSHDATA.html \ + CURLMOPT_PUSHFUNCTION.html PDFPAGES = CURLOPT_ACCEPT_ENCODING.pdf CURLOPT_ACCEPTTIMEOUT_MS.pdf \ CURLOPT_ADDRESS_SCOPE.pdf CURLOPT_APPEND.pdf CURLOPT_AUTOREFERER.pdf \ @@ -328,7 +330,7 @@ PDFPAGES = CURLOPT_ACCEPT_ENCODING.pdf CURLOPT_ACCEPTTIMEOUT_MS.pdf \ CURLMOPT_TIMERDATA.pdf CURLMOPT_TIMERFUNCTION.pdf \ CURLOPT_UNIX_SOCKET_PATH.pdf CURLOPT_PATH_AS_IS.pdf \ CURLOPT_PROXY_SERVICE_NAME.pdf CURLOPT_SERVICE_NAME.pdf \ - CURLOPT_PIPEWAIT.pdf + CURLOPT_PIPEWAIT.pdf CURLMOPT_PUSHDATA.pdf CURLMOPT_PUSHFUNCTION.pdf CLEANFILES = $(HTMLPAGES) $(PDFPAGES) |
