23 .TH CURLOPT_ACCEPT_ENCODING 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
25 CURLOPT_ACCEPT_ENCODING \- enables automatic decompression of HTTP downloads
27 #include <curl/curl.h>
29 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_ACCEPT_ENCODING, char *enc);
31 Pass a char * argument specifying what encoding you'd like.
33 Sets the contents of the Accept-Encoding: header sent in a HTTP request, and
34 enables decoding of a response when a Content-Encoding: header is received.
35 Three encodings are supported: \fIidentity\fP, which does nothing,
36 \fIdeflate\fP which requests the server to compress its response using the
37 zlib algorithm, and \fIgzip\fP which requests the gzip algorithm.
39 If a zero-length string is set like "", then an Accept-Encoding: header
40 containing all built-in supported encodings is sent.
42 You can also opt to just include the Accept-Encoding: header in your request
43 with \fICURLOPT_HTTPHEADER(3)\fP but then there will be no automatic
44 decompressing when receiving data.
46 This is a request, not an order; the server may or may not do it. This option
47 must be set (to any non-NULL value) or else any unsolicited encoding done by
48 the server is ignored. See the special file lib/README.encoding for further
57 This option was called CURLOPT_ENCODING before 7.21.6
59 Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or
60 CURLE_OUT_OF_MEMORY if there was insufficient heap space.
