    This explicit exporting can help with debugging (by making some kinds of experiments easier), or can provide an always-there interface that’s suitable for documenting as part of a board support package. After the GPIO has been exported, gpiod_export_link() allows creating symlinks from elsewhere in sysfs to the GPIO sysfs node. Drivers can ...

sysfs - Wikipedia

    https://en.wikipedia.org/wiki/Sysfs
    sysfs is a pseudo file system provided by the Linux kernel that exports information about various kernel subsystems, hardware devices, and associated device drivers from the kernel's device model to user space through virtual files. In addition to providing information about various devices and kernel subsystems, exported virtual files are also used for their configuration.

    You must have GPIO support in sysfs for this program to work (or you will not see the /sys/class/gpio directory). The gpio-int-test.c program uses poll() to wake up every 3 seconds (using poll() timeout mechanism) at which time it prints a period.
