\&\fIBIO_s_null()\fR returns the null sink \s-1BIO\s0 method. Data written to

the null sink is discarded, reads return \s-1EOF\s0.

.IX Header "NOTES"
|
|
A null sink \s-1BIO\s0 behaves in a similar manner to the Unix /dev/null
|
|
device.
|
|
.PP
|
|
A null bio can be placed on the end of a chain to discard any data
|
|
passed through it.
|
|
.PP
|
|
A null sink is useful if, for example, an application wishes to digest some
|
|
data by writing through a digest bio but not send the digested data anywhere.
|
|
Since a \s-1BIO\s0 chain must normally include a source/sink \s-1BIO\s0 this can be achieved
|
|
by adding a null sink \s-1BIO\s0 to the end of the chain
