# See Global Unlock Sample for sample code.

set zip [new_CkZip]

# Initialize the zip object.  Because we will never actually write a zip file to the filesystem,
# the filepath passed to NewZip does not matter.
set success [CkZip_NewZip $zip "x.zip"]
if {$success != 1} then {
    puts [CkZip_lastErrorText $zip]

# Append a directory tree.  The call to AppendFiles does
# not read the file contents or append them to the zip
# object in memory.  It simply appends references
# to the files so that when WriteBd, WriteZip, or WriteZipAndClose 
# is called, the referenced files are streamed and compressed
# into the .zip output file (or BinData object).

# Write the zip archive into the bdZip object.

# We could directly access the bytes of the zip archive, or perhaps
# get the zip bytes in base64 format.
set zipAsBase64 [CkBinData_getEncoded $bdZip "base64"]
puts "$zipAsBase64"

# Or the zip can be used by some other Chilkat method call that accepts
# a BinData object as an argument.
