+=head1 NAME
+
+X509V3_EXT_print, X509V3_EXT_print_fp - pretty print X509 certificate extensions
+
+=head1 SYNOPSIS
+
+ #include <openssl/x509v3.h>
+
+ int X509V3_EXT_print(BIO *out, X509_EXTENSION *ext, unsigned long flag, int indent);
+ int X509V3_EXT_print_fp(FILE *out, X509_EXTENSION *ext, int flag, int indent);
+
+=head1 DESCRIPTION
+
+X509V3_EXT_print() and X509V3_EXT_print_fp() parse and print the extension
+info from I<ext> to I<bio> or I<out> with indentation set via I<indent>.
+I<flag> determines the behaviour if an extension could not be parsed and can be
+one of:
+B<X509V3_EXT_DEFAULT> (equivalent to 0): an unknown or unparsable extension
+stops the parsing and the function returns a failure.
+B<X509V3_EXT_PARSE_UNKNOWN>: an unknown or unparsable extension is handled by
+printing it through the B<ASN1_parse_dump()> function, and the function returns
+success.
+B<X509V3_EXT_DUMP_UNKNOWN>: an unknown or unparsable extension is handled by
+printing it through the B<BIO_dump_indent()> function, and the function returns
+success,
+B<X509V3_EXT_ERROR_UNKNOWN>: an unknown or unparsable extension is handled by
+printing either "<Not Supported>" or  "<Parse Error>", and the function returns
+success.
+
+=head1 RETURN VALUES
+
+X509V3_EXT_print() and X509V3_EXT_print_fp() return 1 for success and 0 for
+failure.
