NAME

       PEM_X509_INFO_read_bio_ex, PEM_X509_INFO_read_ex - read PEM-encoded data structures into one or more
       X509_INFO objects

SYNOPSIS

        #include <openssl/pem.h>

                                                   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);

DESCRIPTION

       PEM_X509_INFO_read_ex() loads the X509_INFO objects from a file fp.

       PEM_X509_INFO_read_bio_ex() loads the X509_INFO objects using a bio bp.

       Each of the loaded 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 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 sk is NULL a new stack is allocated, else the given stack is extended.

       The optional cb and u parameters can be used for providing a pass phrase needed for decrypting encrypted
       PEM structures (normally only private keys).  See PEM_read_bio_PrivateKey(3) and passphrase-encoding(7)
       for details.

       The library context libctx and property query <propq> are used for fetching algorithms from providers.

RETURN VALUES

       PEM_X509_INFO_read_ex() and PEM_X509_INFO_read_bio_ex() return a stack of X509_INFO objects or NULL on
       failure.
