- PEM object encoding routines
=for comment generic
=head1 SYNOPSIS
#include <openssl/pem.h>
#define DECLARE_PEM_rw(name, TYPE) ...
TYPE *PEM_read_TYPE(FILE *fp, TYPE **a, pem_password_cb *cb, void *u);
TYPE *PEM_read_bio_TYPE(BIO *bp, TYPE **a, pem_password_cb *cb, void *u);
int PEM_write_TYPE(FILE *fp, const TYPE *a);
int PEM_write_bio_TYPE(BIO *bp, const TYPE *a);
=head1 DESCRIPTION
In the description below, I<TYPE> is used
as a placeholder for any of the OpenSSL datatypes, such as I<X509>.
These routines convert between local instances of ASN1 datatypes and
the PEM encoding. For more information on the templates, see
L<ASN1_ITEM(3)>. For more information on the lower-level routines used
by the functions here, see L<PEM_read(3)>.
PEM_read_TYPE() reads a PEM-encoded object of I<TYPE> from the file B<fp>
and returns it. The B<cb> and B<u> parameters are as described in
L<pem_password_cb(3)>.
PEM_read_bio_TYPE() is similar to PEM_read_TYPE() but reads from the BIO B<bp>.
PEM_write_TYPE() writes the PEM encoding of the object B<a> to the file B<fp>.
PEM_write_bio_TYPE() similarly writes to the BIO B<bp>.
=head1 RETURN VALUES
PEM_read_TYPE() and PEM_read_bio_TYPE() return a pointer to an allocated
object, which should be released by calling TYPE_free(), or NULL on error.
PEM_write_TYPE() and PEM_write_bio_TYPE() return the number of bytes written
or zero on error.
