Thanks but that's the source of the confusion because I seem to be
making file upload parts fine using the *PTR* options. The doc for
CURLFORM_BUFFER says "The given string is used as the value of the file
name field ..." while CURLFORM_PTRNAME says "... followed by a string is
used for the name of this part." Thus each of these provides a name,
and each comes with a way to specify the start of the buffer and its length.

So assuming the contents of a file have been read into a buffer, how is
a file upload part prepared with *PTR* different from one using
*BUFFER*? Sorry if I'm being dense.

Thanks,
