Setinterrupt()                                                        XBIOS

Syntax

LONG Setinterrupt( mode, cause )
WORD mode, cause;

Function      Setinterrupt() defines the conditions under which an
              interrupt is generated by the sound system

Opcode        135 (0x87)

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

Parameters    mode configures interrupts to occur when the end of a buffer
              is reached. A value of INT_TIMERA (0) for mode sets Timer A,
              a value of INT_I7 (1) sets the MFP i7 interrupt.
              cause defines the conditions for the interrupt as follows:

              Name        cause  Meaning

              INT_DISABLE   0    Disable interrupt

              INT_PLAY      1    Interrupt at end of play buffer

              INT_RECORD    2    Interrupt at end of record buffer

              INT_BOTH      3    Interrupt at end of both buffers

Binding       move.w   cause,-(sp)
              move.w   mode,-(sp)
              move.w   #$87,-(sp)
              trap     #14
              addq.l   #6,sp

Return Value  Setinterrupt() returns 0 if no error occurred or non-zero
              otherwise.

Comments      If either buffer is in repeat mode, these interrupts can be
              used to double-buffer sounds.
