=head1 NAME

X509_new, X509_free - X509 certificate ASN1 allocation functions

=head1 SYNOPSIS

 #include <openssl/x509.h>

 X509 *X509_new(void);
 void X509_free(X509 *a);

=head1 DESCRIPTION

The X509 ASN1 allocation routines, allocate and free an
X509 structure, which represents an X509 certificate.

X509_new() allocates and initializes a X509 structure.

X509_free() frees up the B<X509> structure B<a>.
If B<a> is NULL nothing is done.

=head1 RETURN VALUES

If the allocation fails, X509_new() returns B<NULL> and sets an error
code that can be obtained by L<ERR_get_error(3)>.
Otherwise it returns a pointer to the newly allocated structure.

X509_free() returns no value.
