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.
