Detailed Description

SSL encoding and decoding functions for network I/O.

Function Documentation

int ssl_timeoutaccept

(

time_t

t

)

accept the request for SSL

Parameters

t	timeout in seconds

Returns

if the call was successful

Return values

0	the call was successful
<0	error code

int ssl_timeoutconn

(

time_t

t

)

establish SSL protocol to remote host

Parameters

t	timeout in seconds

Returns

if the call was successful

Return values

0	the call was successful
<0	error code

static int ssl_timeoutio ( int(*)()  func, time_t  t, char *  buf, const int  len  )

static

call SSL function for given data buffer

Parameters

func	OpenSSL function to call
t	timeout
buf	data buffer
len	length of buf

Returns

if call to func was successful

Return values

>0	the call was successful
<0	error code
-EPROTO	there was a SSL-level protocol error

This function never returns 0.

int ssl_timeoutrehandshake

(

time_t

t

)

do a new SSL handshake

Parameters

t	timeout in seconds

Returns

if handshake was successful

Return values

>0	handshake was successful
<0	error code

int ssl_timeoutwrite ( time_t  t, const char *  buf, const int  len  )

inline

write data SSL encrypted to network

Parameters

t	timeout
buf	data to send
len	length of buf

Returns

return code of SSL_write
