Syntax

LONG Locksnd( VOID )

Function      Locksnd() prevents other applications from simultaneously
              attempting to use the sound system.

Opcode        128 (0x80)

Availability  Available only when bit #2 of the '_SND' cookie is set.

Binding       move.w   #$80,-(sp)
              trap     #14
              addq.l   #2,sp

Return Value  Locksnd() returns 1 if the sound system was successfully
              locked or SNDLOCKED (-129) if the sound system was already
              locked.
