=pod =head1 NAME EVP_PKEY_CTX_get0_libctx, EVP_PKEY_CTX_get0_propq - functions for getting OSSL_LIB_CTX and property query data from an EVP_PKEY_CTX =head1 SYNOPSIS #include <openssl/evp.h> OSSL_LIB_CTX *EVP_PKEY_CTX_get0_libctx(EVP_PKEY_CTX *ctx); const char *EVP_PKEY_CTX_get0_propq(EVP_PKEY_CTX *ctx); =head1 DESCRIPTION The EVP_PKEY_CTX_get0_libctx() and EVP_PKEY_CTX_get0_propq() functions obtain the OSSL_LIB_CTX and property query string values respectively that were associated with the EVP_PKEY_CTX when it was constructed. =head1 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. =head1 SEE ALSO L<EVP_PKEY_CTX_new(3)> =head1 HISTORY All functions were added in OpenSSL 3.0. =head1 COPYRIGHT Copyright 2020 The OpenSSL Project Authors.
