# sk\_wait\_data(9)

wait for data to arrive at sk\_receive\_queue

## NAME

sk\_wait\_data - wait for data to arrive at sk\_receive\_queue

## SYNOPSIS

**int sk\_wait\_data(struct sock \*** *sk***, long \*** *timeo***, const struct sk\_buff \*** *skb***);**

## ARGUMENTS

*sk*

sock to wait on

*timeo*

for how long

*skb*

last skb seen on sk\_receive\_queue

## DESCRIPTION

Now socket state including sk-\>sk\_err is changed only under lock, hence we may omit checks after joining wait queue. We check receive queue before **schedule** only as optimization; it is very likely that **release\_sock** added new data.
