- Echo characters to an Interactive I/O Output device.
-
- The functions assume that isatty() is TRUE at the time they are called.
- Since the UEFI console is a WIDE character device, these functions do all
- processing using wide characters.
-
- It is the responsibility of the caller, or higher level function, to perform
- any necessary translation between wide and narrow characters.

-/** Echo one character to an IIO file.
-
- If character InCh is a special "echo control" character, process it and output
- the resultant character(s), if any. Otherwise pass the character on to the
- IIO_WriteOne() function which performs generic output processing, if needed.
-
- @param[in] filp Pointer to an open IIO file's file descriptor structure.
- @param[in] InCh The wide character to be echoed.
- @param[in] EchoIsOK A flag indicating whether echoing is appropriate for this
- device or not.
-
- @retval -1 The filp argument does not refer to an IIO device.
- Global value errno is set to EINVAL.
- @retval >=0 The number of characters actually output.
