#include <openssl/evp.h> int EVP_PKEY_CTX_set_params(EVP_PKEY_CTX *ctx, const OSSL_PARAM *params); const OSSL_PARAM *EVP_PKEY_CTX_settable_params(const EVP_PKEY_CTX *ctx); int EVP_PKEY_CTX_get_params(EVP_PKEY_CTX *ctx, OSSL_PARAM *params); const OSSL_PARAM *EVP_PKEY_CTX_gettable_params(const EVP_PKEY_CTX *ctx);
EVP_PKEY_CTX_gettable_params() and EVP_PKEY_CTX_settable_params() get a constant OSSL_PARAM(3) array that describes the gettable and settable parameters for the current algorithm implementation, i.e. parameters that can be used with EVP_PKEY_CTX_get_params() and EVP_PKEY_CTX_set_params() respectively. These functions must only be called after the EVP_PKEY_CTX has been initialised for use in an operation.

All other functions and macros described on this page return a positive value for success and 0 or a negative value for failure. In particular a return value of -2 indicates the operation is not supported by the public key algorithm.
