NAME
       ERR_load_strings, ERR_PACK, ERR_get_next_error_library - load arbitrary error strings

SYNOPSIS
	#include <openssl/err.h>

	void 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);

DESCRIPTION
       ERR_load_strings() registers error strings for library number lib.

       str is an array of error string data:

	typedef struct ERR_string_data_st
	{
	       unsigned long error;
	       char *string;
	} ERR_STRING_DATA;

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

       The last entry in the array is {0,0}.

       ERR_get_next_error_library() can be used to assign library numbers to user libraries at runtime.

RETURN VALUE
       ERR_load_strings() returns no value. ERR_PACK() return the error code.  ERR_get_next_error_library() returns a new library number.

HISTORY
       ERR_load_error_strings() and ERR_PACK() are available in all versions of SSLeay and OpenSSL. ERR_get_next_error_library() was added in
       SSLeay 0.9.0.
