NAME
snd_mpu401_uart_new - create an MPU401-UART instance
SYNOPSIS
-
int snd_mpu401_uart_new(struct snd_card * card, int device, unsigned short hardware, unsigned long port, unsigned int info_flags, int irq, int irq_flags, struct snd_rawmidi ** rrawmidi);
ARGUMENTS
card
-
- the card instance
device
-
the device index, zero-based
hardware
-
the hardware type, MPU401_HW_XXXX
port
-
the base address of MPU401 port
info_flags
-
bitflags MPU401_INFO_XXX
irq
-
the irq number, -1 if no interrupt for mpu
irq_flags
-
the irq request flags (SA_XXX), 0 if irq was already reserved.
rrawmidi
-
the pointer to store the new rawmidi instance
DESCRIPTION
Creates a new MPU-401 instance.
Note that the rawmidi instance is returned on the rrawmidi argument, not the mpu401 instance itself. To access to the mpu401 instance, cast from rawmidi->private_data (with struct snd_mpu401 magic-cast).
Returns zero if successful, or a negative error code.
