* Descripton:
|
||||
* The tcsetattr() function sets the parameters associated with the
|
||||
* terminal referred to by the open file descriptor 'fd' from the termios
|
||||
* structure referenced by 'termiop' as follows:
|
||||
*
|
||||
* If 'options' is TCSANOW, the change will occur immediately.
|
||||
*
|
||||
* If 'options' is TCSADRAIN, the change will occur after all output
|
||||
* written to 'fd' is transmitted. This function should be used when changing
|
||||
* parameters that affect output.
|
||||
*
|
||||
* If 'options' is TCSAFLUSH, the change will occur after all
|
||||
* output written to 'fd' is transmitted, and all input so far received but
|
||||
* not read will be discarded before the change is made.
|
||||
*
|
||||
* The tcsetattr() function will return successfully if it was able to
|
||||
* perform any of the requested actions, even if some of the requested
|
||||
* actions could not be performed. It will set all the attributes that
|
||||
* implementation supports as requested and leave all the attributes not
|
||||
* supported by the implementation unchanged. If no part of the request
|
||||
* can be honoured, it will return -1 and set errno to EINVAL.
|
||||
*
|
||||
* The effect of tcsetattr() is undefined if the value of the termios
|
||||
* structure pointed to by 'termiop' was not derived from the result of
|
||||
* a call to tcgetattr() on 'fd'; an application should modify only fields
|
||||
* and flags defined by this specification between the call to tcgetattr()
|
||||
* and tcsetattr(), leaving all other fields and flags unmodified.
|
||||
*
|
||||
* Returned Value:
|
||||
*
|
||||
* Upon successful completion, 0 is returned. Otherwise, -1 is returned
|
||||
* and errno is set to indicate the error. The following errors may be
|
||||
* reported:

*
|
||||
* - EBADF: The 'fd' argument is not a valid file descriptor.
|
||||
* - EINTR: A signal interrupted tcsetattr().
|
||||
* - EINVAL: The 'options' argument is not a supported value, or
|
||||
* an attempt was made to change an attribute represented in the
|
||||
* termios structure to an unsupported value.

||||
* - ENOTTY: The file associated with 'fd' is not a terminal.
