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.

NAME

       gets(), fgets() - get a string from a stream

SYNOPSIS

   Obsolescent Interface
DESCRIPTION

       Reads characters from the standard input stream,
		      into the array pointed to by s, until a new-line character is read or an end-of-file condition is encountered.  The new-line
		      character is discarded and the string is terminated with a null character.

       Reads characters from the
		      stream into the array pointed to by s, until n-1 characters are read, a new-line character is read and transferred to s,	or
		      an end-of-file condition is encountered.	The string is then terminated with a null character.

   Obsolescent Interface
       gets a string from a stream.

APPLICATION USAGE

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

RETURN VALUE

       Upon  successful  completion,  and  return  s.  If the stream is at end-of-file, the end-of-file indicator for the stream is set and a null
       pointer is returned.

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

       If a read error occurs, the error indicator for the stream is set, is set to indicate the error, and a null pointer is returned.

       and can be used to distinguish between an error condition and an end-of-file condition.

ERRORS

       and fail if data needs to be read into the stream's buffer, and:

       The	      flag is set for the file descriptor underlying stream and the process would be delayed in the read operation.

       The file descriptor underlying
		      stream is not a valid file descriptor open for reading.

       The read operation was terminated due to the receipt of a signal,
		      and either no data was transferred or the implementation does not report partial transfer for this file.

       The process is a member of a background process
		      and is attempting to read from its controlling terminal, and either the process is ignoring or blocking the  signal  or  the
		      process group of the process is orphaned.

       Additional values can be set by the underlying function (see read(2)).
