curl_mime_filename - set a mime part's remote file name #include <curl/curl.h> "CURLcode curl_mime_filename(curl_mimepart * " part , "const char * " filename ");" curl_mime_filename(3) sets a mime part's remote file name. When remote file name is set, content data is processed as a file, whatever is the part's content source. A part's remote file name is transmitted to the server in the associated Content-Disposition generated header. part is the part's handle to assign the remote file name to. filename points to the nul-terminated file name string; it may be set to NULL to remove a previously attached remote file name. The remote file name string is copied into the part, thus the associated storage may safely be released or reused after call. Setting a part's file name twice is valid: only the value set by the last call is retained. As long as at least one of HTTP, SMTP or IMAP is enabled. Added in 7.56.0. CURLE_OK or a CURL error code upon failure.
