ERR_load_strings(3)ERR_load_strings(3)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
The ERR_load_strings() function registers error strings for library
number lib.
The 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}.
The ERR_get_next_error_library() function can be used to assign library
numbers to user libraries at runtime.
RETURN VALUE
The ERR_load_strings() function returns no value. The ERR_PACK() func‐
tion returns the error code. The ERR_get_next_error_library() function
returns a new library number.
HISTORY
The ERR_load_error_strings() and ERR_PACK() functions are available in
all versions of SSLeay and OpenSSL. The ERR_get_next_error_library()
function was added in SSLeay 0.9.0.
