.IX Header "DESCRIPTION"
\&\fIERR_put_error()\fR adds an error code to the thread's error queue. It
signals that the error of reason code \fBreason\fR occurred in function
\&\fBfunc\fR of library \fBlib\fR, in line number \fBline\fR of \fBfile\fR.
This function is usually called by a macro.
.PP
\&\fIERR_add_error_data()\fR associates the concatenation of its \fBnum\fR string
arguments with the error code added last.
.PP
ERR_load_strings(3) can be used to register
error strings so that the application can a generate human-readable
error messages for the error code.

no values.

\&\fIERR_put_error()\fR is available in all versions of SSLeay and OpenSSL.
\&\fIERR_add_error_data()\fR was added in SSLeay 0.9.0.
