=head1 DESCRIPTION
|
||
|
|
|
||
|
|
BIO_f_cipher() returns the prefix BIO method. This is a filter for
|
||
|
|
text output, where each line gets automatically prefixed and indented
|
||
|
|
according to user input.
|
||
|
|
|
||
|
|
The prefix and the indentation are combined. For each line of output
|
||
|
|
going through this filter, the prefix is output first, then the amount
|
||
|
|
of additional spaces indicated by the indentation, and then the line
|
||
|
|
itself.
|
||
|
|
|
||
|
|
By default, there is no prefix, and indentation is set to 0.
|
||
|
|
|
||
|
|
BIO_set_prefix() sets the prefix to be used for future lines of
|
||
|
|
text, using I<prefix>. I<prefix> may be NULL, signifying that there
|
||
|
|
should be no prefix. If I<prefix> isn't NULL, this function makes a
|
||
|
|
copy of it.
|
||
|
|
|
||
|
|
BIO_set_indent() sets the indentation to be used for future lines of
|
||
|
|
text, using I<indent>. Negative values are not allowed.
|
||
|
|
|
||
|
|
BIO_get_indent() gets the current indentation.
|
||
|
|
|
||
|
|
=head1 NOTES
|
||
|
|
|
||
|
|
BIO_set_prefix(), BIO_set_indent() and BIO_get_indent() are
|
||
|
|
implemented as macros.
|
||
|
|
|
||
|
|
=head1 RETURN VALUES
|
||
|
|
|
||
|
|
BIO_f_prefix() returns the prefix BIO method.
|
||
|
|
|
||
|
|
BIO_set_prefix() returns 1 if the prefix was correctly set, or <=0 on
|
||
|
|
failure.
|
||
|
|
|
||
|
|
BIO_set_indent() returns 1 if the prefix was correctly set, or <=0 on
|
||
|
|
failure.
|
||
|
|
|
||
|
|
BIO_get_indent() returns the current indentation, or a negative value for failure.
