c++ - How could I read a Shift+Inserted (pasted) string In Linux / g++? -

i know how read keyboard in linux without stopping (like kbhit() behavior under windows). so, whenever returns, know there key-press activity.

then i'll try read key via getch() function.

my question after hit on keyboard, how know shift+insert key combination (paste shortcut ctrl+v in windows) pressed?

as noted, there no globally portable way accomplish because:

• aside special case of linux-specific program uses special calls detect key-presses, program see pasted text — no clues how got there.
• there likewise no clue when paste ended (pastes need not end newline, can words, blanks, etc).

instead, workable solution use posix termios make program's input stream work in raw mode, , set timeout reads. then, program read characters long came "quickly enough" (your decision how quickly).

these related questions show examples of posix termios, including use of timeouts:

• how implement timeout in read function call?
• how simulate “press key continue?”

alternatively, there select call:

• c select() timeout stdin single char (no enter)
