ERR_load_crypto_strings.3ossl - Man Page

load and free error strings


The following functions have been deprecated since OpenSSL 1.1.0, and can be hidden entirely by defining OPENSSL_API_COMPAT with a suitable version value, see openssl_user_macros(7):

 #include <openssl/err.h>

 void ERR_load_crypto_strings(void);
 void ERR_free_strings(void);

 #include <openssl/ssl.h>

 void SSL_load_error_strings(void);


ERR_load_crypto_strings() registers the error strings for all libcrypto functions. SSL_load_error_strings() does the same, but also registers the libssl error strings.

In versions prior to OpenSSL 1.1.0, ERR_free_strings() releases any resources created by the above functions.

Return Values

ERR_load_crypto_strings(), SSL_load_error_strings() and ERR_free_strings() return no values.

The ERR_load_crypto_strings(), SSL_load_error_strings(), and ERR_free_strings() functions were deprecated in OpenSSL 1.1.0 by OPENSSL_init_crypto() and OPENSSL_init_ssl() and should not be used.
