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
prefix.
prefix may be NULL, signifying that there should
be no prefix. If
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
indent. Negative values are not allowed.
BIO_get_indent() gets the current indentation.
BIO_set_prefix(),
BIO_set_indent() and
BIO_get_indent() are
implemented as macros.
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.
