.SH &quot;DESCRIPTION&quot;
.IX Header &quot;DESCRIPTION&quot;
The \fB\s-1BIO_METHOD\s0\fR type is a structure used for the implementation of new \s-1BIO\s0
types. It provides a set of functions used by OpenSSL for the implementation
of the various \s-1BIO\s0 capabilities. See the bio page for more information.
.PP
\&amp;\fIBIO_meth_new()\fR creates a new \fB\s-1BIO_METHOD\s0\fR structure. It should be given a
unique integer \fBtype\fR and a string that represents its \fBname\fR.
Use \fIBIO_get_new_index()\fR to get the value for \fBtype\fR.
.PP
The set of
standard OpenSSL provided \s-1BIO\s0 types is provided in \fBbio.h\fR. Some examples
include \fB\s-1BIO_TYPE_BUFFER\s0\fR and \fB\s-1BIO_TYPE_CIPHER\s0\fR. Filter BIOs should have a
type which have the \*(L&quot;filter\*(R&quot; bit set (\fB\s-1BIO_TYPE_FILTER\s0\fR). Source/sink BIOs
should have the \*(L&quot;source/sink\*(R&quot; bit set (\fB\s-1BIO_TYPE_SOURCE_SINK\s0\fR). File descriptor
based BIOs (e.g. socket, fd, connect, accept etc) should additionally have the
\&amp;\*(L&quot;descriptor\*(R&quot; bit set (\fB\s-1BIO_TYPE_DESCRIPTOR\s0\fR). See the BIO_find_type page for
more information.
.PP
\&amp;\fIBIO_meth_free()\fR destroys a \fB\s-1BIO_METHOD\s0\fR structure and frees up any memory
associated with it.
.PP
\&amp;\fIBIO_meth_get_write_ex()\fR and \fIBIO_meth_set_write_ex()\fR get and set the function
used for writing arbitrary length data to the \s-1BIO\s0 respectively. This function
will be called in response to the application calling \fIBIO_write_ex()\fR or
\&amp;\fIBIO_write()\fR. The parameters for the function have the same meaning as for
\&amp;\fIBIO_write_ex()\fR. Older code may call \fIBIO_meth_get_write()\fR and
\&amp;\fIBIO_meth_set_write()\fR instead. Applications should not call both
\&amp;\fIBIO_meth_set_write_ex()\fR and \fIBIO_meth_set_write()\fR or call \fIBIO_meth_get_write()\fR
when the function was set with \fIBIO_meth_set_write_ex()\fR.
.PP
\&amp;\fIBIO_meth_get_read_ex()\fR and \fIBIO_meth_set_read_ex()\fR get and set the function used
for reading arbitrary length data from the \s-1BIO\s0 respectively. This function will
be called in response to the application calling \fIBIO_read_ex()\fR or \fIBIO_read()\fR.
The parameters for the function have the same meaning as for \fIBIO_read_ex()\fR.
Older code may call \fIBIO_meth_get_read()\fR and \fIBIO_meth_set_read()\fR instead.
Applications should not call both \fIBIO_meth_set_read_ex()\fR and \fIBIO_meth_set_read()\fR
or call \fIBIO_meth_get_read()\fR when the function was set with
\&amp;\fIBIO_meth_set_read_ex()\fR.
.PP
\&amp;\fIBIO_meth_get_puts()\fR and \fIBIO_meth_set_puts()\fR get and set the function used for
writing a \s-1NULL\s0 terminated string to the \s-1BIO\s0 respectively. This function will be
called in response to the application calling \fIBIO_puts()\fR. The parameters for
the function have the same meaning as for \fIBIO_puts()\fR.
.PP
\&amp;\fIBIO_meth_get_gets()\fR and \fIBIO_meth_set_gets()\fR get and set the function typically
used for reading a line of data from the \s-1BIO\s0 respectively (see the \fIBIO_gets\fR\|(3)
page for more information). This function will be called in response to the
application calling \fIBIO_gets()\fR. The parameters for the function have the same
meaning as for \fIBIO_gets()\fR.
.PP
\&amp;\fIBIO_meth_get_ctrl()\fR and \fIBIO_meth_set_ctrl()\fR get and set the function used for
processing ctrl messages in the \s-1BIO\s0 respectively. See the BIO_ctrl page for
more information. This function will be called in response to the application
calling \fIBIO_ctrl()\fR. The parameters for the function have the same meaning as for
\&amp;\fIBIO_ctrl()\fR.
.PP
\&amp;\fIBIO_meth_get_create()\fR and \fIBIO_meth_set_create()\fR get and set the function used
for creating a new instance of the \s-1BIO\s0 respectively. This function will be
called in response to the application calling \fIBIO_new()\fR and passing
in a pointer to the current \s-1BIO_METHOD.\s0 The \fIBIO_new()\fR function will allocate the
memory for the new \s-1BIO,\s0 and a pointer to this newly allocated structure will
be passed as a parameter to the function.
.PP
\&amp;\fIBIO_meth_get_destroy()\fR and \fIBIO_meth_set_destroy()\fR get and set the function used
for destroying an instance of a \s-1BIO\s0 respectively. This function will be
called in response to the application calling \fIBIO_free()\fR. A pointer to the \s-1BIO\s0
to be destroyed is passed as a parameter. The destroy function should be used
for \s-1BIO\s0 specific clean up. The memory for the \s-1BIO\s0 itself should not be freed by
this function.
.PP
\&amp;\fIBIO_meth_get_callback_ctrl()\fR and \fIBIO_meth_set_callback_ctrl()\fR get and set the
function used for processing callback ctrl messages in the \s-1BIO\s0 respectively. See
the \fIBIO_callback_ctrl\fR\|(3) page for more information. This function will be called
in response to the application calling \fIBIO_callback_ctrl()\fR. The parameters for
the function have the same meaning as for \fIBIO_callback_ctrl()\fR.
.SH &quot;RETURN VALUES&quot;
