=head1 NAME
PBMAC1_get1_pbkdf2_param - Function to manipulate a PBMAC1
MAC structure
=head1 SYNOPSIS
#include <openssl/x509.h>
PBKDF2PARAM *PBMAC1_get1_pbkdf2_param(const X509_ALGOR *macalg);
=head1 DESCRIPTION
PBMAC1_get1_pbkdf2_param() retrieves a B<PBKDF2PARAM> structure from an
I<X509_ALGOR> structure.
=head1 RETURN VALUES
PBMAC1_get1_pbkdf2_param() returns NULL in case when PBMAC1 uses an algorithm
apart from B<PBKDF2> or when passed incorrect parameters and a pointer to
B<PBKDF2PARAM> structure otherwise.
=head1 CONFORMING TO

=head1 HISTORY
The I<PBMAC1_get1_pbkdf2_param> function was added in OpenSSL 3.4.
