.... Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.
If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.
Avoid warning from groff about undefined register 'F'.

Title "BIO_meth_new 3"
way too many mistakes in technical documents.
\fIBIO_meth_new() creates a new \s-1BIO_METHOD\s0 structure. It should be given a unique integer type and a string that represents its name. Use BIO_get_new_index() to get the value for type.
The set of standard OpenSSL provided \s-1BIO\s0 types is provided in bio.h. Some examples include \s-1BIO_TYPE_BUFFER\s0 and \s-1BIO_TYPE_CIPHER\s0. Filter BIOs should have a type which have the \*(L"filter\*(R" bit set (\s-1BIO_TYPE_FILTER\s0). Source/sink BIOs should have the \*(L"source/sink\*(R" bit set (\s-1BIO_TYPE_SOURCE_SINK\s0). File descriptor based BIOs (e.g. socket, fd, connect, accept etc) should additionally have the \*(L"descriptor\*(R" bit set (\s-1BIO_TYPE_DESCRIPTOR\s0). See the BIO_find_type page for more information.
\fIBIO_meth_free() destroys a \s-1BIO_METHOD\s0 structure and frees up any memory associated with it.
\fIBIO_meth_get_write() and BIO_meth_set_write() 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 BIO_write(). The parameters for the function have the same meaning as for BIO_write().
\fIBIO_meth_get_read() and BIO_meth_set_read() 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 BIO_read(). The parameters for the function have the same meaning as for BIO_read().
\fIBIO_meth_get_puts() and BIO_meth_set_puts() 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 BIO_puts(). The parameters for the function have the same meaning as for BIO_puts().
\fIBIO_meth_get_gets() and BIO_meth_set_gets() get and set the function typically used for reading a line of data from the \s-1BIO\s0 respectively (see the BIO_gets\|(3) page for more information). This function will be called in response to the application calling BIO_gets(). The parameters for the function have the same meaning as for BIO_gets().
\fIBIO_meth_get_ctrl() and BIO_meth_set_ctrl() 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 BIO_ctrl(). The parameters for the function have the same meaning as for \fIBIO_ctrl().
\fIBIO_meth_get_create() and BIO_meth_set_create() 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 BIO_new() and passing in a pointer to the current \s-1BIO_METHOD.\s0 The BIO_new() 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.
\fIBIO_meth_get_destroy() and BIO_meth_set_destroy() 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 BIO_free(). 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.
\fIBIO_meth_get_callback_ctrl() and BIO_meth_set_callback_ctrl() get and set the function used for processing callback ctrl messages in the \s-1BIO\s0 respectively. See the BIO_callback_ctrl\|(3) page for more information. This function will be called in response to the application calling BIO_callback_ctrl(). The parameters for the function have the same meaning as for BIO_callback_ctrl().
