Hi,

How to use gpio APIs on application user, in main function like gpio_request(110), gpio_direction_ouput() etc ??

if u have any example please provide the link.

I know how to do using kernel module, but i want directly use gpio APIs in application side??

Thanks and regards

I think this is impossible. Why you don't use ioctl or /proc, /sys?

These are Kernel API's and not exported to the User Application, instead you can use GPIO SYSFS interface to configure gpios from user space. Google should provide more info on GPIO_SYSFS option.

Thanks,

Ram,

The calls that you listed are in kernel space. I wrote my own gpio driver, in which the ioctl commands in my driver call the functions you listed.
