reads all remaining bytes from a file, and returns them as a list of integers from 0 to 255.


reads objects of the specified type from a file, until the end of the file is reached. The list of objects read is returned.


reads objects with a sequence of types, until the end of the file is reached.


reads only the first n objects of the specified types.

Details and Options

  • BinaryReadList supports the same types and options as BinaryRead.
  • If file is not already open for reading, BinaryReadList opens it, then closes it when it is finished. If the file is already open, BinaryReadList does not close it at the end.
  • BinaryReadList["file",{type1,}] reads the sequence of typei in order. If the end of file is reached while partway through this sequence, EndOfFile is returned in place of elements in the sequence that have not yet been read.
  • BinaryReadList["!command",] reads from a pipe.
  • BinaryReadList[stream] reads from an open input stream, as returned by OpenRead with BinaryFormat->True.
  • BinaryReadList[File["file"]] is also supported.
  • List of all options
