| curl_mime_addpart - append a new empty part to a mime structure | ||
| .SH SYNOPSIS | ||
| .B #include <curl/curl.h> | ||
| .sp | ||
| .BI "curl_mimepart * curl_mime_addpart(curl_mime * " mime ");" | ||
| .ad | ||
| .SH DESCRIPTION | ||
| curl_mime_addpart() appends a new empty part to the given mime structure and | ||
| returns a handle to it. | ||
| The returned part can be subsequently filled using functions from the mime API. | ||
|
|
||
| \fImime\fP is the handle of the mime structure in which the new part must be | ||
| appended. | ||
| .SH RETURN VALUE | ||
| A mime part structure handle, or NULL upon failure. | ||

| .TH curl_mime_data 3 "22 August 2017" "libcurl 7.56.0" "libcurl Manual" | ||
| .SH NAME | ||
| curl_mime_data - set a mime part's body data from memory | ||
| .SH SYNOPSIS | ||
| .B #include <curl/curl.h> | ||
| .sp | ||
| .BI "CURLcode curl_mime_data(curl_mimepart * " part ", const char * " data | ||
| .BI ", ssize_t " datasize ");" | ||
| .ad | ||
| .SH DESCRIPTION | ||
| curl_mime_data() sets a mime part's body content from memory data. | ||
|
|
||
| \fIdata\fP points to the data bytes: those are copied to the part and their | ||
| storage may safely be reused after call. | ||
| \fIdatasize\fP is the number of data bytes: it can be set to -1 to indicate | ||
| \fIdata\fP is a nul-terminated character string. | ||
| \fIpart\fP is the part's to assign contents to. | ||
|
|
||
| Setting a part's contents twice is valid: only the value set by the last call | ||
| is retained. It is possible to unassign part's contents by setting | ||
| \fIdata\fP to NULL. | ||
|
|
||
| Setting very large data is memory consuming: one might consider using | ||
| \fIcurl_mime_data_cb\fP() in such a case. | ||
| .SH RETURN VALUE | ||
| CURLE_OK or a CURL error code upon failure. | ||
|
|
||
| .SH "SEE ALSO" | ||
