# PDFlib Virtual File system (PVF):
# Create a PVF file which holds an image or PDF, and import the data from the
# PVF file
#
# This avoids disk access and is especially useful when the same image or PDF
# is imported multiply. For examples, images which sit in a database don't
# have to be written and re-read from disk, but can be passed to PDFlib
# directly in memory. A similar technique can be used for loading other data
# such as fonts, ICC profiles, etc.
#
# Required software: PDFlib Lite/PDFlib/PDFlib+PDI/PPS 7
# Required data: image file

#
# Helper function to read the content of a file into a buffer
# avoids incompatible systemcalls
