ERR_LOAD_STRINGS(3)

NAME
ERR_load_strings, ERR_PACK, ERR_get_next_error_library - load arbitrary OpenSSL error strings

SYNOPSIS
#include <openssl/err.h>
void
ERR_load_strings(int lib, ERR_STRING_DATA str[]);
unsigned long
ERR_PACK(int lib, int func, int reason);
int
ERR_get_next_error_library(void);

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, NULL}.

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

RETURN VALUES
ERR_PACK() returns 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.
