Sourceval copy_channels : in_channel -> out_channel -> unit
Sourceval read_all_unless_large : in_channel -> (string, unit) result

Try to read everything from a channel. Returns Error () if the contents are larger than Sys.max_string_length. This is generally a problem only on 32-bit systems. Overflow detection does not happen in the following cases:

  • channel is not a file (for example, a pipe)
  • if the detected size is unreliable (/proc)
  • race condition with another process changing the size of the underlying file. In these cases, an exception might be raised by Buffer functions.
