Take into account c_need_sizeof when evaluating xcb_protocol_request_t.count Incorrect xcb_protocol_request_t.count causes a segmentation fault when calling functions: - xcb_randr_set_monitor{_checked} - xcb_input_change_feedback_control{_checked} - xcb_input_change_device_control{_unchecked} Steps to reproduce: Call xcb_randr_set_monitor() with valid arguments OBSERVED RESULT Segmentation fault ``` Process terminating with default action of signal 11 (SIGSEGV) Access not within mapped region at address 0x780 at 0x4852925: memmove (in /usr/libexec/valgrind/vgpreload_memcheck- amd64-linux.so) by 0x486967C: memcpy (string_fortified.h:29) by 0x486967C: send_request (xcb_out.c:59) by 0x486967C: send_request (xcb_out.c:46) by 0x486967C: xcb_send_request_with_fds64 (xcb_out.c:338) by 0x48699FC: xcb_send_request (xcb_out.c:359) by 0x4891F11: xcb_randr_set_monitor_checked (randr.c:5350) ``` EXPECTED RESULT Function returns cookie Amend: 77b594f9 Signed-off-by:
