5 BIO_s_null - null data sink
9 #include <openssl/bio.h>
11 BIO_METHOD * BIO_s_null(void);
15 BIO_s_null() returns the null sink BIO method. Data written to
16 the null sink is discarded, reads return EOF.
20 A null sink BIO behaves in a similar manner to the Unix /dev/null
23 A null bio can be placed on the end of a chain to discard any data
26 A null sink is useful if, for example, an application wishes to digest some
27 data by writing through a digest bio but not send the digested data anywhere.
28 Since a BIO chain must normally include a source/sink BIO this can be achieved
29 by adding a null sink BIO to the end of the chain
33 BIO_s_null() returns the null sink BIO method.
