- =head1 NAME
- PEM_X509_INFO_read_bio_ex, PEM_X509_INFO_read_ex
- - read PEM-encoded data structures into one or more B<X509_INFO> objects
- =head1 SYNOPSIS
- #include <openssl/pem.h>
- STACK_OF(X509_INFO) *PEM_X509_INFO_read_ex(FILE *fp, STACK_OF(X509_INFO) *sk,
- pem_password_cb *cb, void *u,
- OSSL_LIB_CTX *libctx,
- const char *propq);
- STACK_OF(X509_INFO) *PEM_X509_INFO_read_bio_ex(BIO *bio,
- STACK_OF(X509_INFO) *sk,
- pem_password_cb *cb, void *u,
- OSSL_LIB_CTX *libctx,
- const char *propq);
- =head1 DESCRIPTION
- PEM_X509_INFO_read_ex() loads the B<X509_INFO> objects from a file I<fp>.
- PEM_X509_INFO_read_bio_ex loads the B<X509_INFO> objects using a bio I<bp>.
- Each of the loaded B<X509_INFO> objects can contain a CRL, a certificate,
- and/or a private key.
- The elements are read sequentially, and as far as they are of different type than
- the elements read before, they are combined into the same B<X509_INFO> object.
- The idea behind this is that if, for instance, a certificate is followed by
- a private key, the private key is supposed to correspond to the certificate.
- If the input stack I<sk> is NULL a new stack is allocated,
- else the given stack is extended.
- The optional I<cb> and I<u> parameters can be used for providing a pass phrase
- needed for decrypting encrypted PEM structures (normally only private keys).
- See L<PEM_read_bio_PrivateKey(3)> and L<passphrase-encoding(7)> for details.
- The library context I<libctx> and property query <propq> are used for fetching
- algorithms from providers.
- =head1 RETURN VALUES
- PEM_X509_INFO_read_ex() and PEM_X509_INFO_read_bio_ex() return
- a stack of B<X509_INFO> objects or NULL on failure.

- =head1 HISTORY
- The functions PEM_X509_INFO_read_ex() and
- PEM_X509_INFO_read_bio_ex() were added in OpenSSL 3.0.
