NAME

	AllocSignal -- allocate a signal bit

SYNOPSIS

	signalNum = AllocSignal(signalNum)
D0 D0
BYTE AllocSignal(BYTE);

FUNCTION

	Allocate a signal bit from the current tasks' pool.  Either a
particular bit, or the next free bit may be allocated. The signal
associated with the bit will be properly initialized (cleared). At
least 16 user signals are available per task. Signals should be
deallocated before the task exits.
If the signal is already in use (or no free signals are available)
a -1 is returned.
Allocated signals are only valid for use with the task that
allocated them.

WARNING

	Signals may not be allocated or freed from exception handling code.

INPUTS

	signalNum - the desired signal number {of 0..31} or -1 for no
preference.

RESULT

	signalNum - the signal bit number allocated {0..31}. If no signals
are available, this function returns -1.
