函数原型：static inline int tcp_inq(struct sock *sk)

返回类型：int

参数：

类型参数名称
struct sock *sk
2087  tp等于tcp_sk(sk)
2090  如果1左移sk_state位按位与TCPF_SYN_SENT按位或TCPF_SYN_RECV的值则
2091  answ等于0
2092  否则如果sock_flag(sk, SOCK_URGINLINE)或非 Saved octet of OOB data and control flags 或The next routines deal with comparing 32 bit unsigned ints* and worry about wraparound (automatic with unsigned arithmetic).或非The next routines deal with comparing 32 bit unsigned ints* and worry about wraparound (automatic with unsigned arithmetic).则
2097  answ等于 What we want to receive next 减 Head of yet unread data
2100  如果answ且sock_flag(sk, SOCK_DONE)则answ自减
2102  否则
2103  answ等于 Seq of received urgent pointer 减 Head of yet unread data
