22 .TH curl_mime_type 3 "September 22, 2017" "libcurl 7.59.0" "libcurl Manual"
25 curl_mime_type - set a mime part's content type
27 .B #include <curl/curl.h>
29 .BI "CURLcode curl_mime_type(curl_mimepart * " part ,
30 .BI "const char * " mimetype ");"
33 \fIcurl_mime_type(3)\fP sets a mime part's content type.
35 \fIpart\fP is the part's handle to assign the content type to.
37 \fImimetype\fP points to the nul-terminated file mime type string; it may be
38 set to NULL to remove a previously attached mime type.
40 The mime type string is copied into the part, thus the associated storage may
41 safely be released or reused after call. Setting a part's type twice is valid:
42 only the value set by the last call is retained.
44 In the absence of a mime type and if needed by the protocol specifications,
45 a default mime type is determined by the context:
47 - If set as a custom header, use this value.
49 - application/form-data for a HTTP form post.
51 - If a remote file name is set, the mime type is taken from the file name
52 extension, or application/octet-stream by default.
54 - For a multipart part, multipart/mixed.
56 - text/plain in other cases.
58 As long as at least one of HTTP, SMTP or IMAP is enabled. Added in 7.56.0.
60 CURLE_OK or a CURL error code upon failure.
