kbdputc, kbdq - keyboard interface to cons(3) void kbdputc(Queue *q, int c)

extern Queue *kbdq;

This is the internal interface between cons (3) and the platform-dependent keyboard driver. Before calling any of these functions, the global variable kbdq must be initialised; cons (3) does not initialise it. This is usually done during system initialisation by the keyboard driver's kbdinit or kbdenable function , as follows: .EX kbdq = qopen(4*1024, 0, 0, 0); qnoblock(kbdq, 1);

Kbdputc puts a Unicode character c (ie, a `rune') on the given q , as a sequence of bytes in UTF-8 encoding (see utf (6)). It is up to the platform's keyboard driver to map a physical keyboard character, or a combination of them (for instance, following keyboard (6)) to a given Unicode character.
