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.
