NAME

       fread(), fwrite() - buffered binary input/output to a stream file

SYNOPSIS

   Obsolescent Interfaces
DESCRIPTION

       copies,	into  an  array  pointed to by ptr, up to nitems items of data from the named input stream, where an item of data is a sequence of
       bytes (not necessarily terminated by a null byte) of length size.  stops appending bytes if an end-of-file or error  condition  is  encoun-
       tered while reading stream, or if nitems items have been read.  leaves the file pointer in stream, if defined, pointing to the byte follow-
       ing the last byte read if there is one.	does not change the contents of stream.

       appends at most nitems items of data from the array pointed to by ptr to the named output stream.  stops appending  when  it  has  appended
       nitems items of data or if an error condition is encountered on stream.	does not change the contents of the array pointed to by ptr.

       The argument size is typically where the pseudo-function specifies the length of an item pointed to by ptr.

       and buffered binary input/output to a stream file.

APPLICATION USAGE

       After or is applied to a stream, the stream becomes byte-oriented (see orientation(5)).

RETURN VALUE

       and return the number of items read or written.	If size or nitems is 0, no characters are read or written and 0 is returned.

       The value returned will be less than nitems only if a read error or end-of-file is encountered.

       When  the file corresponding to an open stream gets extended after the end-of-file is reached, any subsequent calls to will succeed and the
       end-of-file indicator will remain set.  However, in the UNIX2003 standards environment (see standards(5)), this function will  return  zero
       and the end-of-file indicator will remain set.

       The or functions must be used to distinguish between an error condition and an end-of-file condition.
