=head1 NAME
X509_SIG_get0, X509_SIG_get0_mutable - DigestInfo functions
=head1 SYNOPSIS
#include <openssl/x509.h>
void X509_SIG_get0(const X509_SIG *sig, const X509_ALGOR **palg,
const ASN1_OCTET_STRING **pdigest);
void X509_SIG_get0_mutable(X509_SIG *sig, X509_ALGOR **palg,
ASN1_OCTET_STRING **pdigest,
=head1 DESCRIPTION
X509_SIG_get0() returns pointers to the algorithm identifier and digest
value in B<sig>. X509_SIG_get0_mutable() is identical to X509_SIG_get0()
except the pointers returned are not constant and can be modified:
for example to initialise them.
