The include file keycode.h¶
This file contains the mnemonic definitions of the keys defined in Section #5 (“Sent by” Sequences) of the terminal parameter file.
The function keycode(0) returns a negative number which is the complement of the terminal parameter file entry number corresponding to the last key pressed, provided that the key is recognised as one of those defined in “Sent by” Sequences. The inchar(0) function works identically.
The function keycode(1) returns immediately with a positive integer which indicates the key that was pressed to exit the last dialog or input command. The value returned is the entry number in the terminal parameter file which corresponds to the recognised key.
The definitions and the numbers they represent are listed below:
