ERR_LOAD_STRINGS(3) Library Functions Manual 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.
