NAME

6       EVP_PKEY_CTX_get0_libctx, EVP_PKEY_CTX_get0_propq,
7       EVP_PKEY_CTX_get0_provider - functions for getting diverse information
8       from an EVP_PKEY_CTX

SYNOPSIS

11        #include <openssl/evp.h>
12
13        OSSL_LIB_CTX *EVP_PKEY_CTX_get0_libctx(EVP_PKEY_CTX *ctx);
14        const char *EVP_PKEY_CTX_get0_propq(const EVP_PKEY_CTX *ctx);
15        const OSSL_PROVIDER *EVP_PKEY_CTX_get0_provider(const EVP_PKEY_CTX *ctx);
16

DESCRIPTION

18       EVP_PKEY_CTX_get0_libctx() and EVP_PKEY_CTX_get0_propq() obtain the
19       OSSL_LIB_CTX and property query string values respectively that were
20       associated with the EVP_PKEY_CTX when it was constructed.
21
22       EVP_PKEY_CTX_get0_provider() returns the provider associated with the
23       ongoing EVP_PKEY_CTX operation.  If the operation is performed by en
24       ENGINE, this function returns NULL.
25

RETURN VALUES

27       EVP_PKEY_CTX_get0_libctx() and EVP_PKEY_CTX_get0_propq() functions
28       return the OSSL_LIB_CTX and property query string associated with the
29       EVP_PKEY_CTX or NULL if they are not set. The returned values should
30       not be freed by the caller.
31
32       EVP_PKEY_CTX_get0_provider() returns a provider if an operation
33       performed by a provider is ongoing, otherwise NULL.
