HPUX fflush[3s]

 fclose(3S)                                                       fclose(3S)





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

 SYNOPSIS
      #include <stdio.h>

      int fclose(FILE *stream);

      int fflush(FILE *stream);

 DESCRIPTION
      fclose() causes any buffered data for the named stream to be written
      out, and the stream to be closed.  Buffers allocated by the standard
      input/output system may be freed.

      fclose() 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, fflush() 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, fflush() performs this flushing action on
      all currently open streams.

 RETURN VALUE
      Upon successful completion, fclose() and fflush() return 0.
      Otherwise, they return EOF and set errno to indicate the error.

 ERRORS
      fclose() and fflush() fail if:

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

           [EBADF]        The file descriptor underlying stream is not
                          valid.

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

           [EINTR]        fclose() or fflush() was interrupted by a signal.

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

 fclose(3S)                                                       fclose(3S)





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

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

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