libusb_set_option() is a variadic function, so the type of the arguments is not clearly defined. When called with LIBUSB_OPTION_LOG_LEVEL, the argument is read with va_arg() as an int, which matches the type used when passing constants, and also most of the internal calls and the calls in the examples. However the internal call site in libusb_init_context() passes the ival element of the libusb_init_option struct directly, which is of type int64_t. This breaks on big-endian architectures like PowerPC, as detected by tests/set_option. Therefore change the libusb_init_option struct to use int here as well. Thanks to Aurelien Jarno for reporting and initial patch. Closes #1416 Closes #1436 Signed-off-by: Tormod Volden <debian.tormod@gmail.com>
libusb
libusb is a library for USB device access from Linux, macOS, Windows, OpenBSD/NetBSD, Haiku, Solaris userspace, and WebAssembly via WebUSB. It is written in C (Haiku backend in C++) and licensed under the GNU Lesser General Public License version 2.1 or, at your option, any later version (see COPYING).
libusb is abstracted internally in such a way that it can hopefully be ported to other operating systems. Please see the PORTING file for more information.
