.SH NAME

curl_mime_data \- set a mime part\(aqs body data from memory

.SH SYNOPSIS
|

|
.nf

#include <curl/curl.h>
|

|
|
||

.SH DESCRIPTION
|
||
|
|
\fIcurl_mime_data(3)\fP sets a mime part\(aqs body content from memory data.
|
||
|
|
|
||
|
|
\fIpart\fP is the mime part to assign contents to, created with
|
||
|
|
\fIcurl_mime_addpart(3)\fP.
|
||
|
|
|
||
|
|
\fIdata\fP points to the data that gets copied by this function. The storage
|
||
|
|
may safely be reused after the call.
|
||
|
|
|
||
|
|
\fIdatasize\fP is the number of bytes \fIdata\fP points to. It can be set to
|
||
|
|
\fICURL_ZERO_TERMINATED\fP to indicate \fIdata\fP is a null\-terminated
|
||
|
|
character string.
|
||
|
|
|
||
|
|
Setting a part\(aqs contents multiple times is valid: only the value set by the
|
||
|
|
last call is retained. It is possible to unassign part\(aqs contents by setting
|
||
|
|
\fIdata\fP to NULL.
|
||
|
|
|
||
|
|
Setting large data is memory consuming: one might consider using
|
||
|
|
\fIcurl_mime_data_cb(3)\fP in such a case.
