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`,
	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 ISA irq number, -1 if not to be allocated
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).

Return

Zero if successful, or a negative error code.
