OPENSSL_CTX, OPENSSL_CTX_new, OPENSSL_CTX_free - OpenSSL library context

=head1 SYNOPSIS

 #include <openssl/crypto.h>

 typedef struct openssl_ctx_st OPENSSL_CTX;

 OPENSSL_CTX *OPENSSL_CTX_new(void);
 void OPENSSL_CTX_free(OPENSSL_CTX *ctx);

=head1 DESCRIPTION

C<OPENSSL_CTX> is an internal OpenSSL library context type.
Applications may allocate their own, but may also use C<NULL> to use
the internal default context with functions that take a C<OPENSSL_CTX>
argument.

OPENSSL_CTX_new() creates a new OpenSSL library context.

OPENSSL_CTX_free() frees the given C<ctx>.

=head1 RETURN VALUES

OPENSSL_CTX_new() return a library context pointer on success, or
C<NULL> on error.

OPENSSL_CTX_free() doesn't return any value.
