#include <termios.h> int tcdrain (int fd); |
This function waits until all the output is written to the file/device referred to by the handle fd. In this implementation, this function does nothing except checking the validity of its arguments; it is provided for compatibility only. Note that the termios emulation handles console only.
Zero on success, nonzero on failure.
