NAME¶OPENSSL_CTX, OPENSSL_CTX_new, OPENSSL_CTX_free, OPENSSL_CTX_load_config - OpenSSL library context
#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);
DESCRIPTION¶"OPENSSL_CTX" is an internal OpenSSL library context type. Applications may allocate their own, but may also use "NULL" to use the internal default context with functions that take a "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 OPENSSL_thread_stop_ex(3) for more information.
OPENSSL_CTX_load_config() loads a configuration file using the given "ctx". This can be used to associate a libctx with providers that are loaded from a configuration.
OPENSSL_CTX_free() frees the given "ctx".
RETURN VALUES¶OPENSSL_CTX_new() return a library context pointer on success, or "NULL" on error.
OPENSSL_CTX_free() doesn't return any value.
HISTORY¶OPENSSL_CTX, OPENSSL_CTX_new(), OPENSSL_CTX_load_config() and OPENSSL_CTX_free() were added in OpenSSL 3.0.
