libressl-ERR_load_strings(3)

Usage

Crypto Library (libcrypto, -lcrypto)

#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);

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.

ERR_PACK() returns the error code. ERR_get_next_error_library() returns a new library number.
