16 GPIO_LINEINFO_CHANGED_READ - Read line info change events for watched lines
31     The buffer to contain the :c:type:`events<gpioline_info_changed>`.
40 Read line info change events for watched lines from the chip.
46     These events relate to changes in a line's request state or configuration,
47     not its value. Use gpio-lineevent-data-read.rst to receive events when a
51 info changed events.  Subsequently, a request, release, or reconfiguration
54 The kernel timestamps events when they occur and stores them in a buffer
57 The size of the kernel event buffer is fixed at 32 events per ``chip_fd``.
59 The buffer may overflow if bursts of events occur quicker than they are read
63 Events read from the buffer are always in the same order that they were
67 To minimize the number of calls required to copy events from the kernel to
68 userspace, `read()` supports copying multiple events. The number of events
