+.Sh DESCRIPTION
+The
+.Nm libgpio
+library provides an interface to configure GPIO pins.
+The library operates with a
+.Ft gpio_handle_t
+opaque type which can be created with
+.Fn gpio_open
+or
+.Fn gpio_open_device .
+When no more GPIO operations are needed, this handle can be destroyed
+with
+.Fn gpio_close .
+.Pp
+To get a list of all available pins, one can call
+.Fn gpio_pin_list .
+This function takes a pointer to a
+.Ft gpio_config_t
+which is dynamically allocated.
+This pointer should be freed with
+.Xr free 3
+when it's no longer necessary.
+.Pp
+The function
+.Fn gpio_pin_config
+retrieves the current configuration of a pin.
+The pin number should be passed in via the
+.Ft g_pin
+variable which is part of the
+.Ft gpio_config_t
+structure.
+.Pp
+The function
+.Fn gpio_pin_set_flags
+configures a pin with the flags passed in by the
+.Ft gpio_config_t
+structure.
+The pin number should also be passed in through the
+.Ft g_pin
+variable.
+All other structure members will be ignored by this function.
+The list of flags can be found in
+.Pa /usr/include/sys/gpio.h .
+.Pp
+The get or set the state of a GPIO pin, the functions
+.Fn gpio_pin_get
+and
+.Fn gpio_pin_set
+are available, respectively.
+To toggle the state, use
+.Fn gpio_pin_toggle .
+.Pp
+The functions
+.Fn gpio_pin_low
+and
+.Fn gpio_pin_high
+are wrappers around
+.Fn gpio_pin_set .
+.Pp
+The functions
+.Fn gpio_pin_input ,
+.Fn gpio_pin_output ,
+.Fn gpio_pin_opendrain ,
+.Fn gpio_pin_pushpull ,
+.Fn gpio_pin_tristate ,
+.Fn gpio_pin_pullup ,
+.Fn gpio_pin_pulldown ,
+.Fn gpio_pin_invin ,
+.Fn gpio_pin_invout
+and
+.Fn gpio_pin_pulsate
+are wrappers around
+.Fn gpio_pin_set_flags .
+.Sh EXAMPLES
+The following example shows how to configure pin 16 as output and then
+drive it high:
+.Bd -literal
+#include <err.h>
+#include <libgpio.h>
+
+gpio_handle_t handle;
+
+handle = gpio_open(0);
+if (handle == GPIO_HANDLE_INVALID)
+ err(1, "gpio_open failed");
+gpio_pin_output(handle, 16);
+gpio_pin_high(handle, 16);
+gpio_close(handle);
+.Ed
+.Pp
+The following example shows how to get a configuration of a pin:
+.Bd -literal
+gpio_config_t cfg;
+
+cfg.g_pin = 32;
+gpio_pin_config(handle, &cfg);
+.Ed
+.Pp
+The structure will contain the name of the pin and its flags.
+.Sh SEE ALSO
+.Xr gpiobus 4 ,
+.Xr gpioctl 8
+.Sh HISTORY
+The
+.Nm libgpio
+library first appeared in
+.Fx 11.0 .
+.Sh AUTHORS
+The
+.Nm libgpio
+library was implemented by
+.An Rui Paulo Aq Mt rpaulo@FreeBSD.org .
