=head1 NAME
|
|
|
|
OPENSSL_CTX, OPENSSL_CTX_new, OPENSSL_CTX_free, OPENSSL_CTX_load_config
|
|
- OpenSSL library context
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/crypto.h>
|
|
|
|
typedef struct openssl_ctx_st OPENSSL_CTX;
|
|
|
|
OPENSSL_CTX *OPENSSL_CTX_new(void);
|
|
int OPENSSL_CTX_load_config(OPENSSL_CTX *ctx, const char *config_file);
|
|
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.
|
|
When a non default library context is in use care should be taken with
|
|
multi-threaded applications to properly clean up thread local resources before
|
|
the OPENSSL_CTX is freed.
|
|
See L<OPENSSL_thread_stop_ex(3)> for more information.
|
|
|
|
OPENSSL_CTX_load_config() loads a configuration file using the given C<ctx>.
|
|
This can be used to associate a libctx with providers that are loaded from
|
|
a configuration.
|
|
|
|
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.
|
|
|
|
=head1 HISTORY
|
|
|
|
OPENSSL_CTX, OPENSSL_CTX_new(), OPENSSL_CTX_load_config() and OPENSSL_CTX_free()
|
|
were added in OpenSSL 3.0.
