__init__(self, infp, file_prefix)
(Constructor)

source code 

FileVolumeWriter initializer

infp is a file object opened for reading. It will be closed at end. file_prefix is the full path of the volumes that will be written. If more than one is required, it will be appended with .1, .2, etc.

write_volume(self, outfp)

source code 

Write self.volume_size bytes from self.infp to outfp

Return None if we have reached end of infp without reaching volume size, and false otherwise.
