- FFLLUUSSHH - Writes data buffered by Fortran output statements to a file
-
- SSYYNNOOPPSSIISS
- UNICOS and UNICOS/mk systems:
- CCAALLLL FFLLUUSSHH((_i_u_n_i_t))
-
- CCAALLLL FFLLUUSSHH((_i_u_n_i_t,,[[_i_s_t_a_t]]))
-
- IRIX systems:
- CCAALLLL FFLLUUSSHH((_i_u_n_i_t,, _i_s_t_a_t))

- FFLLUUSSHH writes to a file any buffered data previously written by Fortran
- output statements. FFLLUUSSHH may be called after reading or writing. The
- current file position is not changed.
-
- When using the CF90 compiler or MIPSpro 7 Fortran 90 compiler on
- UNICOS, UNICOS/mk, or IRIX, all arguments must be of default kind
- unless documented otherwise. On UNICOS and UNICOS/mk, default kind is
- KKIINNDD==88 for integer, real, complex, and logical arguments; on IRIX, the
- default kind is KKIINNDD==44.
-
- This routine has the following arguments:
-
- _i_u_n_i_t Integer variable, expression, or constant containing a
- Fortran unit number. If this value is 101, it flushes the
- unit which is connected to standard output. If this value
- is 102, it flushes the unit which is connected to standard
- error.
-
- _i_s_t_a_t Integer variable or array element that receives the return
- status as follows:
-
- ==00 Indicates that all buffered data, if any, was flushed.
- A file that was immediately read, or a file with a
- buffer that has not changed since the last flush, might
- return a 0 status even though no new data would be
- written to the file.
-
- --11 Indicates that the Fortran unit does not support FFLLUUSSHH,
- and no data was written to the file.
-
- >>00 Indicates that an error condition was encountered. The
- specific error number is returned. Use the eexxppllaaiinn(1)
- command for a description of the error code.
-
- The _i_s_t_a_t argument is optional on UNICOS systems; the user program is
- aborted if FFLLUUSSHH is called without _i_s_t_a_t and an error condition is
- encountered.
-
- NNOOTTEESS
- If FFLLUUSSHH is called with an unconnected unit, an error condition
- results (except for units 101 and 102). Calling FFLLUUSSHH for a file for
- which the program does not have write permission returns a 0 status if
- no data was written to that file previously with Fortran I/O
- statements.
-
- A WWRRIITTEE I/O statement with an asterisk unit identifier (or a PPRRIINNTT
- statement) uses unit 101. See "Fortran I/O Units" in IINNTTRROO__IIOO(3F) on
- UNICOS and UNICOS/mk systems for more information (IINNTTRROO__IIOO is not
- available on IRIX systems).
