.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
One of these functions should be called before generating
textual error messages. However, this is not required when memory
usage is an issue.
.PP
\&\fBERR_free_strings()\fR frees all previously loaded error strings.
.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"
\&\fBERR_load_error_strings()\fR, \fBSSL_load_error_strings()\fR and
\&\fBERR_free_strings()\fR are available in all versions of SSLeay and
OpenSSL.
