SSL_SESSION_SET1_ID_CONTEXT(3)                        Library Functions Manual

NAME
     SSL_SESSION_get0_id_context, SSL_SESSION_set1_id_context - get and set
     the SSL ID context associated with a session

SYNOPSIS
     #include <openssl/ssl.h>

     const unsigned char *
     SSL_SESSION_get0_id_context(const SSL_SESSION *s, unsigned int *len);

     int
     SSL_SESSION_set1_id_context(SSL_SESSION *s, const unsigned char *sid_ctx,
         unsigned int sid_ctx_len);

DESCRIPTION
     SSL_SESSION_get0_id_context() returns the ID context associated with s.
     The length of the ID context in bytes is written to *len if len is not
     NULL.

     SSL_SESSION_set1_id_context() takes a copy of the provided ID context
     given in sid_ctx and associates it with the session s.  The length of the
     ID context is given by sid_ctx_len which must not exceed
     SSL_MAX_SID_CTX_LENGTH bytes.

RETURN VALUES
     SSL_SESSION_get0_id_context() returns an internal pointer to an object
     maintained within s that should not be freed by the caller.

     SSL_SESSION_set1_id_context() returns 1 on success or 0 on error.
