"DESCRIPTION"
Header "DESCRIPTION" \fBEVP_PKEY_CTX_get0_libctx() and EVP_PKEY_CTX_get0_propq() obtain the
\s-1OSSL_LIB_CTX\s0 and property query string values respectively that were
associated with the \s-1EVP_PKEY_CTX\s0 when it was constructed.
\fBEVP_PKEY_CTX_get0_provider() returns the provider associated with the ongoing \s-1EVP_PKEY_CTX\s0 operation. If the operation is performed by en \s-1ENGINE\s0, this function returns \s-1NULL.\s0
"RETURN VALUES"
Header "RETURN VALUES" \fBEVP_PKEY_CTX_get0_libctx() and EVP_PKEY_CTX_get0_propq() functions return the
\s-1OSSL_LIB_CTX\s0 and property query string associated with the \s-1EVP_PKEY_CTX\s0 or \s-1NULL\s0
if they are not set. The returned values should not be freed by the caller.
\fBEVP_PKEY_CTX_get0_provider() returns a provider if an operation performed by a provider is ongoing, otherwise \s-1NULL.\s0
