2 Intel <strong>Fortran</strong> <strong>Libraries</strong> <strong>Reference</strong>SyntaxCALL PXFFDOPEN (ifildes, iunit, access, ierror)ifildes(Input) INTEGER(4). The file descriptor of the opened file.iunit(Input) INTEGER(4). The <strong>Fortran</strong> logical unit to connect to file descriptor ifildes.access(Input) Character. A character string that specifies the attributes for the <strong>Fortran</strong> unit. The stringmust consist of one or more of the following keyword/value pairs. Keyword/value pairs should beseparated by a comma, and blanks are ignored.Keyword Possible Values Description Default'NEWLINE' 'YES' or 'NO' I/O type 'YES''BLANK' 'NULL' or 'ZERO' Interpretation of blanks 'NULL''STATUS' 'OLD', 'SCRATCH', or 'UNKNOWN' File status at open 'UNKNOWN''FORM' 'FORMATTED' or 'UNFORMATTED' Format type 'FORMATTED'Keywords should be separated from their values by the equals ('=') character; for example:call PXFDOPEN (IFILDES, IUNIT, 'BLANK=NULL, STATUS=UNKNOWN', IERROR)ierror(Output) INTEGER(4). The error status.The PXFFDOPEN subroutine connects an external unit identified by iunit to a file descriptorifildes. If the unit is already connected to a file, the file should be closed before usingPXFFDOPEN.NOTE. On Windows* systems, the default value of the POSIX/IO flag is 0,which causes PXFFDOPEN to return an error.To prevent this, call subroutine PXFPOSIXIO and set the value of thePOSIX/IO flag to 1.CompatibilityCONSOLE STANDARD GRAPHICS QUICKWIN GRAPHICS WINDOWS DLL LIB2-286
