hi all,

I am working as a embedded linux developer and i am new to Linux, i am having a doubt in platform driver, can any one give a explanation on the below structure

struct platform_device {
	const char	*name;
	u32		id;
	struct device	dev;
	u32		num_resources;
	struct resource	*resource;
I want to know what is the work of id in the structure if we put -1 for id what does it mean

You might want to give some idea where you found this struct and what you were doing at the time. Linux is quite a large ammount of code and has quite a few uses.
I'm not aware of anything called a 'platform driver' but that doesn't mean it's not familiar to someone else around here.

I would refer to

1 solution

id is most times an "identifier" aka "handle". -1 is often used for "invalid value"

PS: here is a more Windows-flavour forum, so with Linux-question it is not the best place to find
