Description:
C library for interacting with Linux GPIO device - shared libraries
libgpiod encapsulates the ioctl calls and data structures behind a straightforward API. This new character device interface guarantees all allocated resources are freed after closing the device file descriptor and adds several new features that are not present in the obsolete sysfs interface (like event polling, setting/reading multiple values at once or open-source and open-drain GPIOs). . This package contains the required shared libraries.
