Pass a pointer to a linked list of curl_httppost structs as parameter. The easiest way to create such a list, is to use \fIcurl_formadd(3)\fP as documented. The data in this list must remain intact as long as the curl transfer is alive and is using it. Using POST with HTTP 1.1 implies the use of a "Expect: 100-continue" header. You can disable this header with \fICURLOPT_HTTPHEADER(3)\fP. When setting \fICURLOPT_HTTPPOST(3)\fP, it will automatically set \fICURLOPT_NOBODY(3)\fP to 0. This option is deprecated! Do not use it. Use \fICURLOPT_MIMEPOST(3)\fP instead after having prepared mime data. .SH DEFAULT NULL .SH PROTOCOLS HTTP .SH EXAMPLE .nf /* Fill in the file upload field. This makes libcurl load data from the given file name when curl_easy_perform() is called. */ curl_formadd(&formpost, &lastptr, CURLFORM_COPYNAME, "sendfile", CURLFORM_FILE, "postit2.c", CURLFORM_END); /* Fill in the filename field */ curl_formadd(&formpost, &lastptr, CURLFORM_COPYNAME, "filename", CURLFORM_COPYCONTENTS, "postit2.c", CURLFORM_END); /* Fill in the submit field too, even if this is rarely needed */ curl_formadd(&formpost, &lastptr, CURLFORM_COPYNAME, "submit", CURLFORM_COPYCONTENTS, "send", CURLFORM_END); .fi .SH AVAILABILITY As long as HTTP is enabled. Deprecated in 7.56.0. .SH RETURN VALUE Returns CURLE_OK if HTTP is enabled, and CURLE_UNKNOWN_OPTION if not. .SH "SEE ALSO" .BR CURLOPT_POSTFIELDS "(3), " CURLOPT_POST "(3), " CURLOPT_MIMEPOST "(3)," .BR curl_formadd "(3), " curl_formfree "(3), " curl_mime_init "(3)"
