27 Wait for a character to arrive at a filehandle. The filehandle
28 can be either a console handle, or a regular file. For a regular
29 file most filesystems will return a character immediately, but
30 sometimes (for example a network handler) the character may not
34 file - File to wait for a character on.
35 timeout - Number of microseconds to wait for the character
36 to arrive. A value of 0 says to wait indefinately.
38 != 0 if a character arrived before the timeout expired
39 == 0 if no character arrived
42 Many filesystems do not implement this function.
