Hi Kurt,
I think I have a C problem.
I do not understand how the compiler enable to use the pointer ctx.
ctx is not declared in the routine parameters nor in the routine body.
What is the purpose of:
int (*SSL_CTX_sess_get_new_cb(SSL_CTX *ctx))(SSL *ssl, SSL_SESSION *sess)
{
return ctx->new_session_cb;
}
Is it part of the ssl infrastructure or for external user who links with ssl
library ?
Best reagrds,
Zvika

Dear Members,
In the file openssl-1.0.1g\ssl\ssl_sess.c contains the following code:
int (*SSL_CTX_sess_get_new_cb(SSL_CTX *ctx))(SSL *ssl, SSL_SESSION *sess)
{
return ctx->new_session_cb;
}
The return value of this routine is a "pointer to function".
But the code :
ctx->new_session_cb
uses a parameter of the return value. How this is possible ?
The function without return type is:
SSL_CTX_sess_get_new_cb(SSL_CTX *ctx)
The return value is a function that looks like:
int new_session_cb(struct ssl_st *ssl, SSL_SESSION *sess)
I hope that explains it.
I'm trying to compile this code using diab compiler for vxworks6.3 and
I have a syntax error.
Using this compiler for vxWorks 6.9 (newer compiler) gives no syntax
error.
Is there another way to write this code ?
You can make typedefs that might make it easier for you to
understand it, but I would hope that makes no differences for a
compiler.
You could also try to just remove that function in case you don't
need it in your application.
Kurt
