62 | .Ft const BIO_METHOD * | ||

65 | .Fc | ||
66 | .Sh DESCRIPTION | ||
67 | .Fn BIO_f_null | ||
68 | returns the null filter BIO method. | ||
69 | This is a filter BIO that does nothing. | ||
70 | As may be apparent, a null filter BIO is not particularly useful. | ||
71 | .Pp | ||
72 | All requests to a null filter BIO are passed through to the next BIO | ||
73 | in the chain: this means that a BIO chain containing a null filter BIO | ||
74 | behaves just as though the BIO was not there. | ||
75 | .Pp | ||
76 | A chain containing a null filter BIO cannot be copied with | ||
77 | .Xr BIO_dup_chain 3 , | ||
78 | and any attempt to do so fails and returns | ||
79 | .Dv NULL . | ||
80 | .Sh RETURN VALUES | ||
81 | .Fn BIO_f_null | ||
82 | returns the null filter BIO method. | ||
83 | .Pp | ||
84 | When called on a null filter BIO object, | ||
85 | .Xr BIO_method_type 3 | ||
86 | returns the constant | ||
87 | .Dv BIO_TYPE_NULL_FILTER | ||
88 | and | ||
89 | .Xr BIO_method_name 3 | ||
90 | returns a pointer to the static string | ||
91 | .Qq NULL filter , | ||
92 | not to be confused with a NUL string nor with a | ||
93 | .Dv NULL pointer . | ||
