NAME
X509_ALGOR_dup, X509_ALGOR_set0, X509_ALGOR_get0, X509_ALGOR_set_md,
X509_ALGOR_cmp, X509_ALGOR_copy - AlgorithmIdentifier functions
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);
int X509_ALGOR_copy(X509_ALGOR *dest, const X509_ALGOR *src);
DESCRIPTION
X509_ALGOR_dup(3) returns a copy of alg.
X509_ALGOR_set0() sets the algorithm OID of alg to aobj and the
associated parameter type to ptype with value pval. If ptype is
V_ASN1_UNDEF the parameter is omitted, otherwise ptype and pval have
the same meaning as the type and value parameters to ASN1_TYPE_set().
All the supplied parameters are used internally so must NOT be freed
after this call succeeded; otherwise ownership remains with the caller
and alg remains untouched.
X509_ALGOR_get0() is the inverse of X509_ALGOR_set0(): it returns the
algorithm OID in *paobj and the associated parameter in *pptype and
*ppval from the AlgorithmIdentifier alg.
X509_ALGOR_set_md() sets the AlgorithmIdentifier alg to appropriate
values for the message digest md.
X509_ALGOR_cmp() compares a and b and returns 0 if they have identical
encodings and nonzero otherwise.
X509_ALGOR_copy() copies the source values into the dest structs;
making a duplicate of each (and free any thing pointed to from within
*dest).
RETURN VALUES
X509_ALGOR_dup(3) returns a valid X509_ALGOR structure or NULL if an
error occurred.
X509_ALGOR_set0() and X509_ALGOR_copy() return 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 nonzero otherwise.
HISTORY
The X509_ALGOR_copy() was added in 1.1.1e.
