Detailed Description

Header file for the low level input library.

Enumeration Type Documentation

anonymous enum

Enumerator:

R_NULL

R_NULL is sometimes returned by the input when a character was requested but none could be delivered, or when an exception happened.

---

Function Documentation

wchar_t input_common_readch

(

int

timed

)

Function used by input_readch to read bytes from stdin until enough bytes have been read to convert them to a wchar_t.

Conversion is done using mbrtowc. If a character has previously been read and then 'unread' using input_common_unreadch, that character is returned. If timed is true, readch2 will wait at most WAIT_ON_ESCAPE milliseconds for a character to be available for reading before returning with the value WEOF.
