<p>ERR_load_strings, ERR_PACK, ERR_get_next_error_library - load arbitrary error strings</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<pre><code> #include &lt;openssl/err.h&gt;

 int ERR_load_strings(int lib, ERR_STRING_DATA *str);

 int ERR_get_next_error_library(void);

 unsigned long ERR_PACK(int lib, int func, int reason);</code></pre>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>ERR_load_strings() registers error strings for library number <b>lib</b>.</p>

<p><b>str</b> is an array of error string data:</p>

<pre><code> typedef struct ERR_string_data_st
 {
     unsigned long error;
     char *string;
 } ERR_STRING_DATA;</code></pre>

<p>The error code is generated from the library number and a function and reason code: <b>error</b> = ERR_PACK(<b>lib</b>, <b>func</b>, <b>reason</b>). ERR_PACK() is a macro.</p>

<p>The last entry in the array is {0,0}.</p>

<p>ERR_get_next_error_library() can be used to assign library numbers to user libraries at runtime.</p>

<h1 id="RETURN-VALUES">RETURN VALUES</h1>

<p>ERR_load_strings() returns 1 for success and 0 for failure. ERR_PACK() returns the error code. ERR_get_next_error_library() returns zero on failure, otherwise a new library number.</p>
