+.Sh DESCRIPTION
+.Fn ERR_get_error
+returns the earliest error code from the thread's error queue and
+removes the entry.
+This function can be called repeatedly until there are no more error
+codes to return.
+.Pp
+.Fn ERR_peek_error
+returns the earliest error code from the thread's error queue without
+modifying it.
+.Pp
+.Fn ERR_peek_last_error
+returns the latest error code from the thread's error queue without
+modifying it.
+.Pp
+See
+.Xr ERR_GET_LIB 3
+for obtaining information about location and reason of the error, and
+.Xr ERR_error_string 3
+for human-readable error messages.
+.Pp
+.Fn ERR_get_error_line ,
+.Fn ERR_peek_error_line ,
+and
+.Fn ERR_peek_last_error_line
+are the same as the above, but they additionally store the file name and
+line number where the error occurred in
+.Pf * Fa file
+and
+.Pf * Fa line ,
+unless these are
+.Dv NULL .
+.Pp
+.Fn ERR_get_error_line_data ,
+.Fn ERR_peek_error_line_data ,
+and
+.Fn ERR_peek_last_error_line_data
+store additional data and flags associated with the error code in
+.Pf * Fa data
+and
+.Pf * Fa flags ,
+unless these are
+.Dv NULL .
+.Pf * Fa data
+contains a string if
+.Pf * Fa flags Ns & Ns Dv ERR_TXT_STRING
+is true.
+.Pp
+An application
+.Sy MUST NOT
+free the
+.Pf * Fa data
+pointer (or any other pointers returned by these functions) with
+.Xr free 3
+as freeing is handled automatically by the error library.
+.Sh RETURN VALUES
+The error code, or 0 if there is no error in the queue.
