NAME

curl_mime_filename - set a mime part's remote file name

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_mime_filename(curl_mimepart *part,
                            const char *filename);

DESCRIPTION

curl_mime_filename(3) sets a mime part‘s remote filename. When remote filename is set, content data is processed as a file, whatever is the part’s content source. A part's remote filename is transmitted to the server in the associated Content-Disposition generated header.

part is the part's handle to assign the remote filename to.

filename points to the null-terminated filename string; it may be set to NULL to remove a previously attached remote filename.

The remote filename string is copied into the part, thus the associated storage may safely be released or reused after call. Setting a part's file name multiple times is valid: only the value set by the last call is retained.

EXAMPLE


static char imagebuf[]="imagedata"; 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 image data from memory */ curl_mime_data(part, imagebuf, sizeof(imagebuf)); /* set a file name to make it look like a file upload */ curl_mime_filename(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.
