contents, while the ones with PTR in their names simply points to the (static)
data you must make sure remain until curl no longer needs it.
The four options for providing values are: \fBCURLFORM_COPYCONTENTS\fP,
\fBCURLFORM_PTRCONTENTS\fP, \fBCURLFORM_FILE\fP, or \fBCURLFORM_FILECONTENT\fP
followed by a char or void pointer (allowed for PTRCONTENTS).
The options for providing values are: \fBCURLFORM_COPYCONTENTS\fP,
\fBCURLFORM_PTRCONTENTS\fP, \fBCURLFORM_FILE\fP, \fBCURLFORM_BUFFER\fP,
or \fBCURLFORM_FILECONTENT\fP followed by a char or void pointer
(allowed for PTRCONTENTS).
\fBCURLFORM_FILECONTENT\fP does a normal post like \fBCURLFORM_COPYCONTENTS\fP
but the actual value is read from the filename given as a string.

providing multiple \fBCURLFORM_FILE\fP arguments each followed by the filename
(and each FILE is allowed to have a CONTENTTYPE).
\fBCURLFORM_BUFFER\fP
tells libcurl that a buffer is to be used to upload data instead of using a
file. The value of the next parameter is used as the value of the "filename"
parameter in the content header.
\fBCURLFORM_BUFFERPTR\fP
tells libcurl that the address of the next parameter is a pointer to the buffer
containing data to upload. The buffer containing this data must not be freed
until after curl_easy_cleanup is called.
\fBCURLFORM_BUFFERLENGTH\fP
tells libcurl that the length of the buffer to upload is the value of the
next parameter.
Another possibility to send single or multiple files in one section is to use
\fBCURLFORM_ARRAY\fP that gets a struct curl_forms array pointer as its
value. Each structure element has a CURLformoption and a char pointer. For the
