int tcpclient_read ( urg_tcpclient_t cli,
char *  userbuf,
int  req_size,
int  timeout 
)

read from socket.

Parameters:
[in,out]cli: tcp client type variable which must be deallocated by a caller after closing.
[out]userbuf: buffer to store read data which must be allocated by a caller.
[in]req_size,:data size requested to read in byte.
[in]timeout: time out specification which unit is microsecond.
Returns:
the number of data read, -1 when error.

[in]buf_size,:data size requested to read in byte.
[in]timeout: time out specification which unit is microsecond.
Returns:
the number of data read, -1 when error.

Definition at line 292 of file urg_tcpclient.c.

Returns:
returns the number of data wrote, -1 when error.
