.Nd configure files and directories used by a certificate store
.Sh SYNOPSIS
.In openssl/x509_vfy.h
.Ft int
.Fo X509_STORE_load_locations
.Fa "X509_STORE *store"

.Sh DESCRIPTION
.Fn X509_STORE_load_locations
instructs the
.Fa store
to use the PEM file
.Fa file
and all the PEM files in the directories
contained in the colon-separated list
.Fa dirs
for looking up certificates, in addition to files and directories
that are already configured.
Directories already in use are not added again.
If
.Dv NULL
is passed for
.Fa file
or
.Fa dirs ,
no new file or no new directories are added, respectively.
.Pp
.Fn X509_STORE_load_locations
is identical to
.Xr SSL_CTX_load_verify_locations 3
except that it operates directly on an
.Vt X509_STORE
object, rather than on the store used by an SSL context.
See that manual page for more information.
.Pp
.Fn X509_STORE_set_default_paths
is similar except that it instructs the
.Fa store
to use the default PEM file and directory
(as documented in
.Sx FILES )
in addition to what is already configured.
It ignores errors that occur while trying to load the file or to
add the directory, but it may still fail for other reasons, for
example when out of memory while trying to allocate the required
.Vt X509_LOOKUP
objects.
.Pp
.Fn X509_STORE_set_default_paths
is identical to
.Xr SSL_CTX_set_default_verify_paths 3
except that it operates directly on an
.Vt X509_STORE
object, rather than on the store used by an SSL context.
See that manual page for more information.
.Sh RETURN VALUES
.Fn X509_STORE_load_locations
returns 1 if all files and directories specified were successfully
added.
It returns 0 for failure.
That can happen if adding the file failed, if adding any of the
directories failed, or if both arguments were
.Dv NULL .
.Pp
.Fn X509_STORE_set_default_paths
returns 0 for some error conditions and 1 otherwise, not just for
success, but also for various cases of failure.
.Sh FILES
.Bl -tag -width Ds
.It Pa /etc/ssl/cert.pem
default PEM file for
.Fn X509_STORE_set_default_paths
.It Pa /etc/ssl/certs/
default directory for
.Fn X509_STORE_set_default_paths
.El
.Sh SEE ALSO
.Xr SSL_CTX_load_verify_locations 3 ,
.Xr X509_LOOKUP_hash_dir 3 ,
.Xr X509_STORE_set1_param 3 ,
.Xr X509_STORE_set_verify_cb 3
.Sh BUGS
By the time that adding a directory is found to have failed,
the file and some other directories may already have been successfully loaded,
so these functions may change the state of the store even when they fail.
.Pp
.Fn X509_STORE_set_default_paths
clears the error queue, deleting even error information that was
already present when it was called.
