ERR_LOAD_STRINGS(3) OpenSSL ERR_LOAD_STRINGS(3)

ERR_load_strings, ERR_PACK, ERR_get_next_error_library - load arbitrary error strings

#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);

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.

ERR_load_strings() returns no value. ERR_PACK() return the error code. ERR_get_next_error_library() returns zero on failure, otherwise a new library number.
