This module will contain part of a Fortran API to functions detailed in ISO/IEC 9945-1:1990 Portable Operating System Interface (POSIX) - Part 1: System Application Program Interface (API) [C Language].
In this release only the
FLUSH procedure is supported.
Users are advised to use the
ONLY clause when using this module, as it
will have further names added in later releases.
Error handling is described in
Note that for procedures with an optional
ERRNO argument, if an error
ERRNO is not present, the program will be terminated.
All procedures in this module are generic and may also be specific (this may change in a future release).
SUBROUTINE FLUSH(LUNIT,ERRNO) INTEGER(*),INTENT(IN) :: LUNIT INTEGER(ERROR_KIND),OPTIONAL,INTENT(OUT) :: ERRNOFlushes the output buffer of logical unit
LUNIT. The effect is similar to the Fortran 2003
FLUSHstatement, except that the statement allows flushing a unit which is not connected but the procedure does not.
LUNIT is not a valid unit number or is not connected to a file,
EBADF is raised (see
