dot operator before member variable

77
hi,
I have seen . operator used while defining structure before name of variable?
ex.
struct usb_driver stub_driver = {
.name = "usbip",
.probe = stub_probe,
.disconnect = stub_disconnect,
.id_table = stub_table,
};
What is that, does someone know?

Not in standard C89 or C++ you haven't.

This is a part of the C99 standard and it allows you to specifically initialise members of a structure, all other members of the structure are initialised to 0.

The . is just part of the syntax for this type of initialisaer and comes before the structure member name.

But then what is the type of those variables?....data type?? char,float,int??
Is it the case that it takes its type according to initialized value of it?

No , their types are already specified in struct usb_driver structure.
