インテル® Fortran コンパイラー 19.0 デベロッパー・ガイドおよびリファレンス
Statement: Causes data written to a file to become available to other processes or causes data written to a file outside of Fortran to be accessible to a READ statement. It takes one of the following forms:
FLUSH([UNIT=]io-unit [, ERR=label] [, IOMSG=msg-var] [IOSTAT=i-var])
FLUSH io-unit
io-unit |
(Input) Is an external unit specifier. |
label |
(Input) Is the label of the branch target statement that receives control if an error occurs. |
msg-var |
(Output) Is a scalar default character variable that is assigned an explanatory message if an I/O error occurs. |
i-var |
(Output) Is a scalar integer variable that is defined as a positive integer if an error occurs and zero if no error occurs. |
The FLUSH statement specifiers can appear in any order. An I/O unit must be specified, but the UNIT= keyword is optional if the unit specifier is the first item in the I/O control list.
This statement has no effect on file position.
