#
# Results:
#	When -multiple is set to 0, this returns the absolute pathname
#	of the selected file. (NOTE: This is not the same as a single
#	element list.)
# 
#	When -multiple is set to > 0, this returns a Tcl list of absolute
#       pathnames. The argument for -multiple is ignored, but for consistency
#       with Windows it defines the maximum amount of memory to allocate for
#       the returned filenames.
