C++ (Cpp) _fdt_check_prop_offset Examples

Example #1

File: fdt_ro.c Project: hsienchieh/uefilab

int fdt_next_property_offset(const void *fdt, int offset)
{
	if ((offset = _fdt_check_prop_offset(fdt, offset)) < 0)
		return offset;

	return _nextprop(fdt, offset);
}

Example #2

File: fdt_ro.c Project: BadrElh/open-amp

const struct fdt_property *fdt_get_property_by_offset(const void *fdt,
						      int offset, int *lenp)
{
	int err;
	const struct fdt_property *prop;

	if ((err = _fdt_check_prop_offset(fdt, offset)) < 0) {
		if (lenp)
			*lenp = err;
		return NULL;
	}

	prop = _fdt_offset_ptr(fdt, offset);

	if (lenp)
		*lenp = fdt32_to_cpu(prop->len);

	return prop;
}

Example #3

File: fdt_ro.c Project: fehead/linux_m
