flush(3)                            CLIX                            flush(3)



  NAME

    flush - Flushes the output for the specified FORTRAN logical unit

  LIBRARY

    FORTRAN library (libap_f.a)

  SYNOPSIS

    integer i, lun
    i = flush (lun)

  DESCRIPTION

    The flush command flushes the output for the specified FORTRAN logical
    unit.  The FORTRAN library utilizes the buffered I/O functions fopen(),
    fread(), fwrite(), and so on, for logical unit I/O.  Thus, after a FORTRAN
    write statement is executed, some or all data may reside in a buffer and
    will not necessarily have been written to the device or file associated
    with the logical unit.  Data will always be flushed when the program exits
    or a logical unit is closed.  However, when a user requires data to be
    flushed to a device or file immediately, flush() is provided.

  RETURN VALUES

    Upon successful completion, the FORTRAN logical unit number is returned.
    Otherwise, a value of -1 is returned.
