NAME

SSL_new, SSL_up_ref — create a new SSL structure for a connection

SYNOPSIS

library “libssl” libcrypto
#include <openssl/ssl.h> SSL *
SSL_new(SSL_CTX *ctx); int
SSL_up_ref(SSL *ssl);

DESCRIPTION

SSL_new() creates a new SSL structure which is needed to hold the data for a TLS/SSL connection. The new structure inherits the settings of the underlying context ctx: connection method, options, verification settings, timeout settings, security level. The reference count of the new structure is set to 1. SSL_up_ref() increments the reference count of ssl by 1.

RETURN VALUES

The following return values can occur:

NULL

The creation of a new SSL structure failed. Check the error stack to find out the reason.

Pointer to an SSL structure

The return value points to an allocated SSL structure.

SSL_up_ref() returns 1 for success or 0 for failure.
