.Sh DESCRIPTION
.Fn X509_STORE_set1_param
copies the verification parameters from
.Fa pm
using
.Xr X509_VERIFY_PARAM_set1 3
into the verification parameter object contained in the
.Fa store .
.Pp
.Fn X509_VERIFY_PARAM_set_flags ,
.Fn X509_STORE_set_purpose ,
.Fn X509_STORE_set_trust ,
and
.Fn X509_STORE_set_depth
call
.Fn X509_VERIFY_PARAM_set_flags ,
.Fn X509_VERIFY_PARAM_set_purpose ,
.Fn X509_VERIFY_PARAM_set_trust ,
and
.Fn X509_VERIFY_PARAM_set_depth
on the verification parameter object contained in the
.Fa store .
.Pp
.Fn X509_STORE_add_cert
and
.Fn X509_STORE_add_crl
add the certificate
.Fa x
or the certificate revocation list
.Fa crl
to the
.Fa store ,
increasing its reference count by 1 in case of success.
Untrusted objects should not be added in this way.
.Pp
.Fn X509_STORE_get_ex_new_index ,
.Fn X509_STORE_set_ex_data ,
and
.Fn X509_STORE_get_ex_data
handle application specific data in
.Vt X509_STORE
objects.
Their usage is identical to that of
.Xr RSA_get_ex_new_index 3 ,
.Xr RSA_set_ex_data 3 ,
and
.Xr RSA_get_ex_data 3 .
.Fn X509_STORE_get_ex_new_index
is implemented as a macro.
.Sh RETURN VALUES
.Fn X509_STORE_set1_param ,
.Fn X509_STORE_set_purpose ,
.Fn X509_STORE_set_trust ,
and
.Fn X509_STORE_set_ex_data
return 1 for success or 0 for failure.
.Pp
.Fn X509_STORE_set_flags
and
.Fn X509_STORE_set_depth
always return 1, indicating success.
.Pp
.Fn X509_STORE_add_cert
and
.Fn X509_STORE_add_crl
return 1 for success or 0 for failure.
For example, they fail if
.Fa x
or
.Fa crl
is a
.Dv NULL
pointer, if a certificate with the same subject name as
.Fa x
or a revocation list with the same issuer name as
.Fa crl
are already contained in the
.Fa store ,
or if memory allocation fails.
.Pp
.Fn X509_STORE_get0_param
returns an internal pointer to the verification parameter object
contained in the
.Fa store .
The returned pointer must not be freed by the calling application.
.Pp
.Fn X509_STORE_get1_objects
returns a newly allocated stack containing
the certificates, revocation lists, and private keys in
.Fa store ,
as well as cached objects added by
.Xr X509_LOOKUP_hash_dir 3 .
The caller must release the result with
.Xr sk_pop_free 3
and
.Xr X509_OBJECT_free 3
when done.
.Pp
.Fn X509_STORE_get0_objects
is a deprecated function returning an internal pointer to
the stack of certificates, revocation lists, and private keys contained in
.Fa store .
The returned pointer must not be modified or freed by the calling application.
This function is not thread-safe.
If
.Fa store
is shared across multiple threads, callers cannot safely inspect the result of
this function, because another thread may have concurrently added to it.
In particular,
.Xr X509_LOOKUP_hash_dir 3
treats this list as a cache and may add to it in the course of certificate
verification.
.Pp
.Fn X509_STORE_get_ex_new_index
returns a new index or \-1 on failure.
.Pp
.Fn X509_STORE_get_ex_data
returns the application data or
.Dv NULL
on failure.
