=head1 NAME

ERR_load_crypto_strings, SSL_load_error_strings, ERR_free_strings -
load and free error strings

=head1 SYNOPSIS

The following functions have been deprecated since OpenSSL 1.1.0, and can be
hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value,
see L<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);

=head1 DESCRIPTION

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

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

=head1 RETURN VALUES

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

=head1 SEE ALSO

L<ERR_error_string(3)>

=head1 HISTORY

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.
