X509_ALGOR_dup, X509_ALGOR_set0, X509_ALGOR_get0, X509_ALGOR_set_md, X509_ALGOR_cmp - AlgorithmIdentifier functions

=head1 SYNOPSIS

 #include <openssl/x509.h>

 X509_ALGOR *X509_ALGOR_dup(X509_ALGOR *alg);
 int X509_ALGOR_set0(X509_ALGOR *alg, ASN1_OBJECT *aobj, int ptype, void *pval);
 void X509_ALGOR_get0(const ASN1_OBJECT **paobj, int *pptype,
                      const void **ppval, const X509_ALGOR *alg);
 void X509_ALGOR_set_md(X509_ALGOR *alg, const EVP_MD *md);
 int X509_ALGOR_cmp(const X509_ALGOR *a, const X509_ALGOR *b);

=head1 DESCRIPTION

X509_ALGOR_dup() returns a copy of B<alg>.

X509_ALGOR_set0() sets the algorithm OID of B<alg> to B<aobj> and the
associated parameter type to B<ptype> with value B<pval>. If B<ptype> is
B<V_ASN1_UNDEF> the parameter is omitted, otherwise B<ptype> and B<pval> have
the same meaning as the B<type> and B<value> parameters to ASN1_TYPE_set().
All the supplied parameters are used internally so must B<NOT> be freed after
this call.

X509_ALGOR_get0() is the inverse of X509_ALGOR_set0(): it returns the
algorithm OID in B<*paobj> and the associated parameter in B<*pptype>
and B<*ppval> from the B<AlgorithmIdentifier> B<alg>.

X509_ALGOR_set_md() sets the B<AlgorithmIdentifier> B<alg> to appropriate
values for the message digest B<md>.

X509_ALGOR_cmp() compares B<a> and B<b> and returns 0 if they have identical
encodings and non-zero otherwise.

=head1 RETURN VALUES

X509_ALGOR_dup() returns a valid B<X509_ALGOR> structure or NULL if an error
occurred.

X509_ALGOR_set0() returns 1 on success or 0 on error.

X509_ALGOR_get0() and X509_ALGOR_set_md() return no values.

X509_ALGOR_cmp() returns 0 if the two parameters have identical encodings and
non-zero otherwise.
