# See Global Unlock Sample for sample code.

$mime = chilkat::CkMime->new();

# In this example, we have a MIME file containing 8bit (non-encoded) binary data,
# and it is what I call "headless".  MIME is headless when it omits
# the top-level header.  The file we have here begins with the first
# boundary string.

# The structure the MIME to be loaded is:

# multipart/mixed (inferred because it is headless)
#     application/xop+xml
#     image/jpeg
#     image/gif
#     image/gif
# 

$success = $mime->LoadMimeFile("qa_data/mime/headless_binary_soap_mtom_mime.mim");
if ($success != 1) {
    print $mime->lastErrorText() . "\r\n";
    exit;
}
