71 reads PEM-formatted (RFC 1421) data from the BIO
73 for the data type given in
75 (RSA PRIVATE KEY, CERTIFICATE, etc.).
76 If multiple PEM-encoded data structures are present in the same stream,
77 .Fn PEM_bytes_read_bio
78 will skip non-matching data types and continue reading.
79 Non-PEM data present in the stream may cause an error.
81 The PEM header may indicate that the following data is encrypted; if so,
82 the data will be decrypted, waiting on user input to supply a passphrase

90 Some data types have compatibility aliases, such as a file containing
91 X509 CERTIFICATE matching a request for the deprecated type CERTIFICATE.
92 The actual type indicated by the file is returned in

108 .Fn PEM_bytes_read_bio
109 returns 1 for success or 0 for failure.
