TYPE_get_ex_data(TYPE *d, int idx);

DESCRIPTION

In the description here, TYPE is used a placeholder for any of the OpenSSL datatypes listed in CRYPTO_get_ex_new_index(3). These functions handle application-specific data in OpenSSL data structures. Their usage is identical to that of RSA_get_ex_new_index(3), RSA_set_ex_data(3), and RSA_get_ex_data(3). TYPE_get_ex_new_index() is a macro that calls CRYPTO_get_ex_new_index(3) with the correct index value. TYPE_set_ex_data() is a function that calls CRYPTO_set_ex_data(3) with an offset into the opaque exdata part of the TYPE object. TYPE_get_ex_data() is a function that calls CRYPTO_get_ex_data(3) with an offset into the opaque exdata part of the TYPE object.

RETURN VALUES

TYPE_get_new_ex_index() returns a new index on success or -1 on error. TYPE_set_ex_data() returns 1 on success or 0 on error. TYPE_get_ex_data() returns the application data or NULL if an error occurred.
