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
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 runtime.
RETURN VALUE
ERR_load_strings() returns no value. ERR_PACK() return 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.
