POSIX Subroutine: Discards terminal input data, output data, or both.
Module: USE IFPOSIX
Syntax
CALL PXFTCFLUSH (ifildes, iaction, ierror)
ifildes
(Input) INTEGER(4). The file descriptor associated with the terminal.
iaction
(Input) INTEGER(4). The action to perform.
ierror
(Output) INTEGER(4). The error status.
If successful, ierror is set to zero; otherwise, an error code.
The action performed depends on the value of iaction, which must be one of the following constant names:
| Constant1 | Action | |
|---|---|---|
| TCIFLUSH | Discards all data that has been received but not read. | |
| TCOFLUSH | Discards all data that has been written but not transmitted. | |
| TCIOFLUSH | Discards both data received but not read and data written but not transmitted. (Performs TCIFLUSH and TCOFLUSH actions.) | |
| 1 These names can be used in PXFCONST or IPXFCONST. | ||
