typedef struct filock { struct flock set; /* contains type, start, and end */ union { int wakeflg; /* for locks sleeping on this one */ struct { long sysid; pid_t pid; } blk; /* for sleeping locks only */ } stat; struct filock *prev; struct filock *next; } filock_t;此结构定义于<sys/flock.h>,用于管理文件锁相关信息。set结构体包含锁的类型、起始和结束位置等关键信息。stat联合体包含唤醒标志或用于睡眠锁的系统ID和进程ID。prev和next指针用于构建链表,方便管理多个文件锁。
