termkey_start3
Enable or disable terminal operations
Usage
#include <termkey.h> int termkey_start(TermKey *tk); int termkey_stop(TermKey *tk); int termkey_is_started(TermKey *tk);
Link with -ltermkey.
Overview
termkey_start() enables the terminal IO operations of the given termkey(7) instance, including sending a terminal control sequence and setting the termios(3) modes required.
termkey_stop() disables terminal IO operations, by reversing the steps taken by termkey_start(). A newly-constructed termkey instance will have terminal IO enabled already.
termkey_is_started() enquires whether terminal IO is currently enabled.
Return value
If successful, termkey_start() and termkey_stop() return a true value. On failure, zero is returned with errno set to indicate the failure. termkey_is_started() returns true or false to indicate whether terminal IO is currently enabled.
