.SH SYNOPSIS
.IX Header "SYNOPSIS"
The following functions have been deprecated since OpenSSL 1.1.0, and can be
hidden entirely by defining \fBOPENSSL_API_COMPAT\fR with a suitable version value,
see \fBopenssl_user_macros\fR\|(7):

.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBERR_load_crypto_strings()\fR registers the error strings for all
\&\fBlibcrypto\fR functions. \fBSSL_load_error_strings()\fR does the same,
but also registers the \fBlibssl\fR error strings.
.PP
In versions prior to OpenSSL 1.1.0,
\&\fBERR_free_strings()\fR releases any resources created by the above functions.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBERR_load_crypto_strings()\fR, \fBSSL_load_error_strings()\fR and
\&\fBERR_free_strings()\fR return no values.

.SH HISTORY
.IX Header "HISTORY"
The \fBERR_load_crypto_strings()\fR, \fBSSL_load_error_strings()\fR, and
\&\fBERR_free_strings()\fR functions were deprecated in OpenSSL 1.1.0 by
\&\fBOPENSSL_init_crypto()\fR and \fBOPENSSL_init_ssl()\fR and should not be used.
