=head1 NAME |
|
|
|
BIO_s_null - null data sink |
|
|
|
=head1 SYNOPSIS |
|
|
|
#include <openssl/bio.h> |
|
|
|
BIO_METHOD * BIO_s_null(void); |
|
|
|
=head1 DESCRIPTION |
|
|
|
BIO_s_null() returns the null sink BIO method. Data written to |
|
the null sink is discarded, reads return EOF. |
|
|
|
=head1 NOTES |
|
|
|
A null sink BIO behaves in a similar manner to the Unix /dev/null |
|
device. |
|
|
|
A null bio can be placed on the end of a chain to discard any data |
|
passed through it. |
|
|
|
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 BIO chain must normally include a source/sink BIO this can be achieved |
|
by adding a null sink BIO to the end of the chain |
|
