SYNOPSIS
#include <openssl/pem.h>
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);
DESCRIPTION
In the description below, TYPE is used as a placeholder for any of the
OpenSSL datatypes, such as X509. The macro DECLARE_PEM_rw expands to
the set of declarations shown in the next four lines of the synopsis.
These routines convert between local instances of ASN1 datatypes and
the PEM encoding. For more information on the templates, see
ASN1_ITEM(3). For more information on the lower-level routines used by
the functions here, see PEM_read(3).
PEM_read_TYPE() reads a PEM-encoded object of TYPE from the file fp and
returns it. The cb and u parameters are as described in
pem_password_cb(3).
PEM_read_bio_TYPE() is similar to PEM_read_TYPE() but reads from the
BIO bp.
PEM_write_TYPE() writes the PEM encoding of the object a to the file
fp.
PEM_write_bio_TYPE() similarly writes to the BIO bp.
NOTES
These functions make no assumption regarding the pass phrase received
from the password callback. It will simply be treated as a byte
sequence.
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.
