EVP_PKEY_CTX_GET0_LIBCTX(3ossl) OpenSSL EVP_PKEY_CTX_GET0_LIBCTX(3ossl)
NAME
EVP_PKEY_CTX_get0_libctx, EVP_PKEY_CTX_get0_propq,
EVP_PKEY_CTX_get0_provider - functions for getting diverse information
from an EVP_PKEY_CTX
SYNOPSIS
#include <openssl/evp.h>
OSSL_LIB_CTX *EVP_PKEY_CTX_get0_libctx(EVP_PKEY_CTX *ctx);
const char *EVP_PKEY_CTX_get0_propq(const EVP_PKEY_CTX *ctx);
const OSSL_PROVIDER *EVP_PKEY_CTX_get0_provider(const EVP_PKEY_CTX *ctx);
DESCRIPTION
EVP_PKEY_CTX_get0_libctx() and EVP_PKEY_CTX_get0_propq() obtain the
OSSL_LIB_CTX and property query string values respectively that were
associated with the EVP_PKEY_CTX when it was constructed.
EVP_PKEY_CTX_get0_provider() returns the provider associated with the
ongoing EVP_PKEY_CTX operation. If the operation is performed by en
ENGINE, this function returns NULL.
RETURN VALUES
EVP_PKEY_CTX_get0_libctx() and EVP_PKEY_CTX_get0_propq() functions
return the OSSL_LIB_CTX and property query string associated with the
EVP_PKEY_CTX or NULL if they are not set. The returned values should
not be freed by the caller.
EVP_PKEY_CTX_get0_provider() returns a provider if an operation
performed by a provider is ongoing, otherwise NULL.
