EVP_PKEY_CTX_get0_libctx(3)         OpenSSL        EVP_PKEY_CTX_get0_libctx(3)



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

LIBRARY
       libcrypto, -lcrypto

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.
