These functions handle application specific data in X509_STORE_CTX 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).

This mechanism is used internally by the ssl(3) library to store the SSL structure associated with a verification operation in an X509_STORE_CTX structure.

() and () are macros calling () and (), respectively, with an idx of 0.

X509_STORE_CTX_get_ex_new_index() returns a new index or -1 on failure.

X509_STORE_CTX_set_ex_data() and X509_STORE_CTX_set_app_data() return 1 on success or 0 on failure.

X509_STORE_CTX_get_ex_data() and X509_STORE_CTX_get_app_data() return the application data or NULL on failure. NULL may also be valid application data, but currently these functions can only fail if given an invalid idx argument.

X509_STORE_CTX_set_app_data() and X509_STORE_CTX_get_app_data() first appeared in SSLeay 0.8.0 and X509_STORE_CTX_get_ex_new_index(), X509_STORE_CTX_set_ex_data(), and X509_STORE_CTX_get_ex_data() in SSLeay 0.9.0. All these functions have been available since OpenBSD 2.4.
