# 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 runtime.

# 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.
