🎀 Detailed Description 🎀

This library contains usb information. that's it, that's the whole personality. she knows about your USB devices and she's not shy about it 💜

👑 DATA STRUCTURES 👑

🧚 Structure pDriverInfoList

Structure pDriverInfoList contains information related to a usb information:

typedef struct driver_list {
     struct driver_info *data;
    struct driver_list *next;
}  DriverInfoList, *pDriverInfoList;

There are other members not documented here, which are only meant for libkyusb internal use. 🙈 do not perceive them, they're shy, mind your business bestie.

🍓 Structure driver_info

Structure driver_info contains information related to a usb information:

typedef struct driver_info {
     char name[32]; //名称
    char type[2 + 1]; //类型
    char pid[4 + 1];
    char vid[4 + 1];
    char serialNo[32]; //序列号
    char devNode[32]; //路径
} DriverInfo, *pDriverInfo;

There are other members not documented here, which are only meant for libkyusb internal use. same energy, same energy. 🙈✨

look at those fixed-size char arrays. 32 for the name, 2 + 1 for the type, 4 + 1 for the pid and vid (the + 1 is for the null terminator, the way she said "I need room to breathe" 😭). serialNo and devNode get their 32 too. no cap.
