NAME

ERR_load_strings, ERR_PACK, ERR_get_next_error_library - load arbitrary error strings

SYNOPSIS

#include <openssl/err.h>
int 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 run time.

RETURN VALUES

ERR_load_strings() returns 1 for success and 0 for failure. ERR_PACK() returns the error code. ERR_get_next_error_library() returns zero on failure, otherwise a new library number.
