HOWTO". It explains how MIN (t->c_cc[VMIN] || vmin_) and TIME
(t->c_cc[VTIME] || vtime_) is to be used.
In non-canonical input processing mode, input is not assembled into
lines and input processing (erase, kill, delete, etc.) does not
occur. Two parameters control the behavior of this mode: c_cc[VTIME]
sets the character timer, and c_cc[VMIN] sets the minimum number of
characters to receive before satisfying the read.
If MIN > 0 and TIME = 0, MIN sets the number of characters to receive
before the read is satisfied. As TIME is zero, the timer is not used.
If MIN = 0 and TIME > 0, TIME serves as a timeout value. The read will
be satisfied if a single character is read, or TIME is exceeded (t =
TIME *0.1 s). If TIME is exceeded, no character will be returned.
If MIN > 0 and TIME > 0, TIME serves as an inter-character timer. The
read will be satisfied if MIN characters are received, or the time
between two characters exceeds TIME. The timer is restarted every time
a character is received and only becomes active after the first
character has been received.
If MIN = 0 and TIME = 0, read will be satisfied immediately. The
number of characters currently available, or the number of characters
requested will be returned. According to Antonino (see contributions),
you could issue a fcntl(fd, F_SETFL, FNDELAY); before reading to get
the same result.
