DESCRIPTION
       X509_STORE_set_verify_cb() sets the verification callback of ctx to
       verify_cb overwriting the previous callback.  The callback assigned
       with this function becomes a default for the one that can be assigned
       directly to the corresponding X509_STORE_CTX, please see
       X509_STORE_CTX_set_verify_cb(3) for further information.

       X509_STORE_set_verify() sets the final chain verification function for
       ctx to verify.  Its purpose is to go through the chain of certificates
       and check that all signatures are valid and that the current time is
       within the limits of each certificate's first and last validity time.
       The final chain verification functions must return 0 on failure and 1
       on success.  If no chain verification function is provided, the
       internal default function will be used instead.

       X509_STORE_set_get_issuer() sets the function to get the issuer
       certificate that verifies the given certificate x.  When found, the
       issuer certificate must be assigned to *issuer.  This function must
       return 0 on failure and 1 on success.  If no function to get the issuer
       is provided, the internal default function will be used instead.

       X509_STORE_set_check_issued() sets the function to check that a given
       certificate x is issued with the issuer certificate issuer.  This
       function must return 0 on failure (among others if x hasn't been issued
       with issuer) and 1 on success.  If no function to get the issuer is
       provided, the internal default function will be used instead.

       X509_STORE_set_check_revocation() sets the revocation checking
       function.  Its purpose is to look through the final chain and check the
       revocation status for each certificate.  It must return 0 on failure
       and 1 on success.  If no function to get the issuer is provided, the
       internal default function will be used instead.

       X509_STORE_set_get_crl() sets the function to get the crl for a given
       certificate x.  When found, the crl must be assigned to *crl.  This
       function must return 0 on failure and 1 on success.  If no function to
       get the issuer is provided, the internal default function will be used
       instead.

       X509_STORE_set_check_crl() sets the function to check the validity of
       the given crl.  This function must return 0 on failure and 1 on
       success.  If no function to get the issuer is provided, the internal
       default function will be used instead.

       X509_STORE_set_cert_crl() sets the function to check the revocation
       status of the given certificate x against the given crl.  This function
       must return 0 on failure and 1 on success.  If no function to get the
       issuer is provided, the internal default function will be used instead.

       X509_STORE_set_check_policy() sets the function to check the policies
       of all the certificates in the final chain..  This function must return
       0 on failure and 1 on success.  If no function to get the issuer is
       provided, the internal default function will be used instead.

       X509_STORE_set_lookup_certs() and X509_STORE_set_lookup_crls() set the
       functions to look up all the certs or all the CRLs that match the given
       name nm.  These functions return NULL on failure and a pointer to a
       stack of certificates (X509) or to a stack of CRLs (X509_CRL) on
       success.  If no function to get the issuer is provided, the internal
       default function will be used instead.

       X509_STORE_set_cleanup() sets the final cleanup function, which is
       called when the context (X509_STORE_CTX) is being torn down.  This
       function doesn't return any value.  If no function to get the issuer is
       provided, the internal default function will be used instead.

       X509_STORE_get_verify_cb(), X509_STORE_CTX_get_verify(),
       X509_STORE_get_get_issuer(), X509_STORE_get_check_issued(),
       X509_STORE_get_check_revocation(), X509_STORE_get_get_crl(),
       X509_STORE_get_check_crl(), X509_STORE_set_verify(),
       X509_STORE_set_get_issuer(), X509_STORE_get_cert_crl(),
       X509_STORE_get_check_policy(), X509_STORE_get_lookup_certs(),
       X509_STORE_get_lookup_crls() and X509_STORE_get_cleanup() all return
       the function pointer assigned with X509_STORE_set_check_issued(),
       X509_STORE_set_check_revocation(), X509_STORE_set_get_crl(),
       X509_STORE_set_check_crl(), X509_STORE_set_cert_crl(),
       X509_STORE_set_check_policy(), X509_STORE_set_lookup_certs(),
       X509_STORE_set_lookup_crls() and X509_STORE_set_cleanup(), or NULL if
       no assignment has been made.

       X509_STORE_set_verify_cb_func(), X509_STORE_set_verify_func() and
       X509_STORE_set_lookup_crls_cb() are aliases for
       X509_STORE_set_verify_cb(), X509_STORE_set_verify() and
       X509_STORE_set_lookup_crls, available as macros for backward
       compatibility.

NOTES
       All the callbacks from a X509_STORE are inherited by the corresponding
       X509_STORE_CTX structure when it is initialized.  See
       X509_STORE_CTX_set_verify_cb(3) for further details.

BUGS
       The macro version of this function was the only one available before
       OpenSSL 1.0.0.

RETURN VALUES
       The X509_STORE_set_*() functions do not return a value.

       The X509_STORE_get_*() functions return a pointer of the appropriate
       function type.
