curldown is this new file format for libcurl man pages. It is markdown inspired with differences: - Each file has a set of leading headers with meta-data - Supports a small subset of markdown - Uses .md file extensions for editors/IDE/GitHub to treat them nicely - Generates man pages very similar to the previous ones - Generates man pages that still convert nicely to HTML on the website - Detects and highlights mentions of curl symbols automatically (when their man page section is specified) tools: - cd2nroff: converts from curldown to nroff man page - nroff2cd: convert an (old) nroff man page to curldown - cdall: convert many nroff pages to curldown versions - cd2cd: verifies and updates a curldown to latest curldown This setup generates .3 versions of all the curldown versions at build time. CI: Since the documentation is now technically markdown in the eyes of many things, the CI runs many more tests and checks on this documentation, including proselint, link checkers and tests that make sure we capitalize the first letter after a period...

# NAME
|
|
|
|
curl_mime_filedata - set a mime part's body data from a file contents
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_mime_filedata(curl_mimepart *part,
|
|
const char *filename);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
curl_mime_filedata(3) sets a mime part's body content from the named
|
|
file's contents. This is an alternative to curl_mime_data(3) for setting
|
|
data to a mime part.
|
|
|
|
*part* is the part's to assign contents to.
|
|
|
|
*filename* points to the null-terminated file's path name. The pointer can
|
|
be NULL to detach the previous part contents settings. Filename storage can
|
|
be safely be reused after this call.
|
|
|
|
As a side effect, the part's remote file name is set to the base name of the
|
|
given *filename* if it is a valid named file. This can be undone or
|
|
overridden by a subsequent call to curl_mime_filename(3).
|
|
|
|
The contents of the file is read during the file transfer in a streaming
|
|
manner to allow huge files to get transferred without using much memory. It
|
|
therefore requires that the file is kept intact during the entire request.
|
|
|
|
If the file size cannot be determined before actually reading it (such as for
|
|
a character device or named pipe), the whole mime structure containing the
|
|
part is transferred using chunks by HTTP but is rejected by IMAP.
|
|
|
|
Setting a part's contents multiple times is valid: only the value set by the
|
|
last call is retained.

# EXAMPLE
|
|
|
|
~~~c
|
|
int main(void)
|
|
{
|
|
curl_mime *mime;
|
|
curl_mimepart *part;
|
|
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
/* create a mime handle */
|
|
mime = curl_mime_init(curl);
|
|
|
|
/* add a part */
|
|
part = curl_mime_addpart(mime);
|
|
|
|
/* send data from this file */
|
|
curl_mime_filedata(part, "image.png");
|
|
|
|
/* set name */
|
|
curl_mime_name(part, "data");
|
|
}
|
|
}

# AVAILABILITY
|
|
|
|
As long as at least one of HTTP, SMTP or IMAP is enabled. Added in 7.56.0.
|
|
|
|
# RETURN VALUE
|
|
|
|
CURLE_OK or a CURL error code upon failure. CURLE_READ_ERROR is only an
|
|
indication that the file is not yet readable: it can be safely ignored at
|
|
this time, but the file must be made readable before the pertaining
|
|
easy handle is performed.
