21 X509_ALGOR_dup() returns a copy of B<alg>.
23 X509_ALGOR_set0() sets the algorithm OID of B<alg> to B<aobj> and the
24 associated parameter type to B<ptype> with value B<pval>. If B<ptype> is
25 B<V_ASN1_UNDEF> the parameter is omitted, otherwise B<ptype> and B<pval> have
26 the same meaning as the B<type> and B<value> parameters to ASN1_TYPE_set().
27 All the supplied parameters are used internally so must B<NOT> be freed after
30 X509_ALGOR_get0() is the inverse of X509_ALGOR_set0(): it returns the
31 algorithm OID in B<*paobj> and the associated parameter in B<*pptype>
32 and B<*ppval> from the B<AlgorithmIdentifier> B<alg>.
34 X509_ALGOR_set_md() sets the B<AlgorithmIdentifier> B<alg> to appropriate
35 values for the message digest B<md>.
37 X509_ALGOR_cmp() compares B<a> and B<b> and returns 0 if they have identical
38 encodings and nonzero otherwise.
40 X509_ALGOR_copy() copies the source values into the dest structs; making
41 a duplicate of each (and free any thing pointed to from within *dest).
45 X509_ALGOR_dup() returns a valid B<X509_ALGOR> structure or NULL if an error
48 X509_ALGOR_set0() and X509_ALGOR_copy() return 1 on success or 0 on error.
50 X509_ALGOR_get0() and X509_ALGOR_set_md() return no values.
52 X509_ALGOR_cmp() returns 0 if the two parameters have identical encodings and
57 The X509_ALGOR_copy() was added in 1.1.1e.
