If \fIptype\fR is +\&\fBV_ASN1_UNDEF\fR the parameter is omitted, otherwise \fIptype\fR and \fIpval\fR have +the same meaning as the \fItype\fR and \fIvalue\fR parameters to \fBASN1_TYPE_set()\fR. +All the supplied parameters are used internally so must \fBNOT\fR be freed after +this call succeeded; +otherwise ownership remains with the caller and \fIalg\fR remains untouched. +.PP +\&\fBX509_ALGOR_get0()\fR is the inverse of \fBX509_ALGOR_set0()\fR: it returns the +algorithm OID in \fI*paobj\fR and the associated parameter in \fI*pptype\fR +and \fI*ppval\fR from the \fBAlgorithmIdentifier\fR \fIalg\fR. +.PP +\&\fBX509_ALGOR_set_md()\fR sets the \fBAlgorithmIdentifier\fR \fIalg\fR to appropriate +values for the message digest \fImd\fR. +.PP +\&\fBX509_ALGOR_cmp()\fR compares \fIa\fR and \fIb\fR and returns 0 if they have identical +encodings and nonzero otherwise. +.PP +\&\fBX509_ALGOR_copy()\fR copies the source values into the dest structs; making +a duplicate of each (and free any thing pointed to from within *dest). +.SH "RETURN VALUES" +.IX Header "RETURN VALUES" +\&\fBX509_ALGOR_dup()\fR returns a valid \fBX509_ALGOR\fR structure or NULL if an error +occurred. +.PP +\&\fBX509_ALGOR_set0()\fR and \fBX509_ALGOR_copy()\fR return 1 on success or 0 on error. +.PP +\&\fBX509_ALGOR_get0()\fR and \fBX509_ALGOR_set_md()\fR return no values. +.PP +\&\fBX509_ALGOR_cmp()\fR returns 0 if the two parameters have identical encodings and +nonzero otherwise. +.SH HISTORY +.IX Header "HISTORY" +The \fBX509_ALGOR_copy()\fR was added in 1.1.1e. +.SH COPYRIGHT +.IX Header "COPYRIGHT" +Copyright 2002\-2022 The OpenSSL Project Authors.
