# NAME

OSSL_ITEM - OpenSSL Core type for generic itemized data

# SYNOPSIS

     #include <openssl/core.h>

     typedef struct ossl_item_st OSSL_ITEM;
     struct ossl_item_st {
         unsigned int id;
         void *ptr;
     };

# DESCRIPTION

This type is a tuple of integer and pointer. It's a generic type used as a generic descriptor, its exact meaning being defined by how it's used. Arrays of this type are passed between the OpenSSL libraries and the providers, and must be terminated with a tuple where the integer is zero and the pointer NULL.

This is currently mainly used for the return value of the provider's error reason strings array, see provider-base(7)/Provider Functions.
