function_description(opl_minte.c)
[minte module]


local function declaration

ssize_t opl_minte_read (struct file *filp, char *buffer, size_t length, loff_t *offset)
 description: copy the opl_chip_irq_pending(indicate which interrupt occured) to user App, which will handle its interrupt.if the no irq pending occured,the process will sleep until the isr wake up it.
ssize_t opl_minte_write (struct file *filp, const char *buffer, size_t length, loff_t *offset)
 description: because the enable irq or disable irq will be in atomic mode,so it should be operated in kernel mode is correct.
