NAME

	WaitForChar -- Determine if chars arrive within a time limit

SYNOPSIS

	status = WaitForChar( file, timeout )
D0 D1 D2
BOOL WaitForChar(BPTR, LONG)

FUNCTION

	If a character is available to be read from 'file' within the
time (in microseconds) indicated by 'timeout', WaitForChar()
returns -1 (TRUE). If a character is available, you can use Read()
to read it. Note that WaitForChar() is only valid when the I/O
stream is connected to a virtual terminal device. If a character is
not available within 'timeout', a 0 (FALSE) is returned.

BUGS

	Due to a bug in the timer.device in V1.2/V1.3, specifying a timeout
of zero for WaitForChar() can cause the unreliable timer & floppy
disk operation.

INPUTS

	file - BCPL pointer to a file handle
timeout - integer

RESULT

	status - boolean

Read(), FGetC()
