NAME
       fclose(), fflush(), fclose_unlocked(), fflush_unlocked() - close or flush a stream

SYNOPSIS
   Obsolescent Interfaces
DESCRIPTION
       causes any buffered data for the named stream to be written out, and the stream to be closed.  Buffers allocated by the standard input/out-
       put system may be freed.

       is performed automatically for all open files upon calling exit(2).

       If stream points to an output stream or an update stream in which the most recent operation was output, causes any buffered  data  for  the
       stream to be written to that file; otherwise any buffered data is discarded.  The stream remains open.

       If stream is a null pointer, performs this flushing action on all currently open streams.

   Obsolescent Interfaces
       and close or flush a stream.

RETURN VALUE
       Upon successful completion, and return 0.  Otherwise, they return EOF and set to indicate the error.

ERRORS
       If or fails, is set to one of:

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

	      The file descriptor underlying
			stream is not valid.

	      An attempt was made to write a file
			that exceeds the process's file size limit or the maximum file size (see ulimit(2)).

	      or	was interrupted by a signal.

	      The process is in a background process group
			and  is  attempting to write to its controlling terminal, is set, the process is neither ignoring nor blocking the signal,
			and the process group of the process is orphaned.

	      There was no free space remaining on the device containing the file.

	      An attempt was made to write to a pipe
			that is not open for reading by any process.  A signal is also sent to the process.

       Additional values may be set by the underlying and functions (see write(2), lseek(2) and close(2)).
